Honda Antenna Adapter

Plug n play and good antenna quality and strength.

Pros: Easy to plug in

Cons: none

Works if installed correctly, Blue wire to switched 12v

2007 Honda Pilot
Crutchfield Customer Review (What's this?)

This is the first time I found CF's instructions to be incorrect, at least for my 07 Honda Pilot. The Blue wire has to be connected to the same switched 12v *usually red* in the harness, and the plug into the factory plug-in. If connected as they requested to the power antenna the radio reception will be horrible.

Pros: Works fine Good reception Picks up digital info

Cons: Wires into 12v in my case, a step I've never seen.

Must have for the Ridgeline

Written by: Chris from North Carolina on December 29, 2015

2006 Honda Ridgeline
Crutchfield Customer Review (What's this?)

Once I figured out that on my vehicle (Honda Ridgeline) the blue wire needs 12v power all was well. Instructions had me wire it to the remote wire and did not supply my antenna's booster with enough power. Wiring it this way in my truck gave me no reception at all. Fortunately, someone in a forum somewhere steered me in the right direction.

Pros: ease of installation

Cons: poor instructions related to my specific vehicle

Crutchfield Customer Review (What's this?)

This worked well after figuring out the blue wire is connected to the antenna remote on the radio. I do not have a retracting antenna but it is required to power an amplifier in line or something because it did not work until connected. No hookup instruction with the adapter.

Pros: It Worked!

Cons: No installation instructions.

Perfect antenna adapter

Written by: garfy from Hawaii on August 30, 2015

Crutchfield Customer Review (What's this?)

The antenna adapter plugged into the OEM antenna connector perfectly, thus connecting the new stereo to the factory antenna harness. The blue power antenna wire was unused as these Fits don't have any power antenna (just the short rubber duckie on the rear of the roof.

Pros: Plugs in and works like the OEM connector

A Must for a Ridgeline

Written by: Austin from South Carolina on April 14, 2015

2007 Honda Ridgeline
Crutchfield Customer Review (What's this?)

This is an absolute must for first generation Ridgelines, but be sure to connect the blue wire to a 12v line from your head unit or the vehicle. The stock antenna in the Ridgeline is built into the roof, and it requires power for the signal booster to work correctly. This adapter makes it very simple.

Pros: Easy to install, plenty of lead.

Cons:

This worked great. The remote amp turn on and antenna wire needed to be spliced together into the same wire on the harness (and this was not made clear in the documentation) but when things are put together right, all is well.

Pros: Works great.

Cons: The remote amp turn on and antenna wire needed to be spliced together into the same wire on the harness (and this was not made clear in the documentation provided with the wiring harness and/or the head unit). This itself is not a con, but the lack of clarification is the con.

Crutchfield Customer Review (What's this?)

This product works great, but I wasn't sure initially what to do with the blue wire. Install was on a 2013 Honda Fit Sport and the blue wire needs to be connected in order to power the antenna. Made the mistake of not connecting it which means that AM stations will not come in and FM are noisy and hit or miss. Just a suggestion that Crutchfield should point that out in the instructions.

Pros: Works. Make sure to find out if your install requires the blue wire.

Cons: Crutchfield needs to highlight that the blue wire may be needed. I did not see that in the instructions.

Not a whole lot to say, other than it worked well for me. Fits the 2012 Honda Insight. As others have said and I found out, connect the blue wire to the remote wire in your wiring harness. The Honda Insight doesn't have a power antenna per se, but my understanding is the blue wire powers a mini-amp at the base of the antenna that improves the reception of certain stations/frequencies.

This works, but you need to attach the blue wire to the _switched_ +12V if your radio doesn't have a dedicated antenna control wire.

Should be ok but I wasn't sure which wire goes to the one with this adapter. Turns out I hooked up the wrong one so no FM right now. I need to rewire that to connect to the power wire from the head unit and not the vehicle harness.

Pros: Should be good. Maybe clear instructions on where the blue wire needs to connect.

Cons: No instructions.

2007 Honda Civic EX
Crutchfield Customer Review (What's this?)

Mine came sans directions. A quick tech-support call uncovered the purpose of the blue wire; it's to power an antenna amp, which Honda uses to supplement the signal from the glass-embedded antenna. Once the antenna blue wire is soldered to the (Kenwood) radio blue/white switched-power wire, signal strength was restored to what might be expected.

Pros: works

Cons: no directions, especially for the blue wire, which powers an antenna amp

Blue Wire

Crutchfield Customer Review (What's this?)

Works great. Excellent reception. I used this with a Pioneer AVIC-X930BT and the Honda/Acura Receiver Harness/adapter, Crutchfield Item# 120701721. The blue wire on the antenna adapter connects to the blue wire on the Honda Receiver AND the blue wire from the Pioneer receiver harness. Without that third blue wire from the Pioneer harness, the reception was terrible.

Hooked up easily but the radio signal is weaker than it was with my stock radio in my Honda Ridgeline especially on AM. Not a big deal for me as I rarely listen to AM radio but worth noting none the less.

Pros: Easy to install. Called Crutchfield about the blue wire.

Cons: Weaker AM radio signal than the stock radio connection. This could be either the antenna connector or the radio.

Crutchfield Customer Review (What's this?)

Finally managed to find it in the box. The instructions were poor. I had to call Crutchfield to find out what to do with the blue wire and was told a lot of people call about it, because you must connect it to the blue-white wire of the harness, or you don't get any radio reception. A simple instruction update would solve the matter, because as I was told by tech support, a lot of people disgregard the wire, then have to tear out the install and connect it, after they call tech support and complain of poor radio reception.

Pros: Worked fine when hooked up correctly.

Cons: Instructions need to be updated and clarified.

Crutchfield Customer Review (What's this?)

OK Crutchfield, I've found your build sheet instuctions helpful in the past but you guys dropped the ball on this one. I used this adapter to install a HU on an 08 Civic and got no AM reception and poor FM reception. Turns out the blue wire is not a power antenna lead but an antenna amplifier lead. Honda's antenna amp is not passive so it lets almost no signal through if it is not powered. With ZERO instuctions on what to do with this blue wire I left it unhooked and was so unhappy with my radio reception I was ready to return it. From looking at the reviews here, this is a common problem. With the blue wire hooked to the power antenna lead from the HU my radio sounds great and I am happy with it.

Pros: It does what it is supposed to do when its hooked up right.

Cons: Zero instructions on the blue wire that MUST be used with cars with an antenna amplifier. Nothing in the build sheet told me I had an antenna amplifier.

I decided to do my homework before attempting to install my new Kenwood (KDC-352U), since I saw a lot of gripes from other reviewed about the lack of instructions and not knowing what to do with the blue wire.

According to crutchfield tech support, this is conneccted to the Kendwood's harness wire with the dark blue/white stripe (P. CONT)

I plan on installing my stereo this weekend, but thought I'd share this information with others to save the hassle of calling for support.

It works. There was an extra wire hanging off of it that wasn't really explained in the directions, but I figured it was probably for a power antenna. I do have to say the FM reception on the clarion unit I used this with is much worse than the factory unit it replaced, but I can't say whether it's the fact it's using this adapter or if it's the unit itself.

Pros: Does what it's supposed to do.

This is pretty standard fare. Does what it's supposed to do. TIP: when you are using this adapter, you do not need the antenna wire in the Honda adapter harness. I guess you can wire all 3 together but that one in the Honda20 harness won't go anywhere.

Good product but poor installation instructions. I did not read the reviews and found nothing in the installation guide to direct me about connecting the blue wire to the power antennae wire.

Crutchfield Customer Review (What's this?)

As many other reviewers have stated, watch out for the blue cable; it attaches to the "Power Ant" of the aftermarket head unit. The blue cable sends a booster signal for the antenna, so without it you'd get extremely poor reception--especially from the HD radio stations. Other than that, the adapter is a no brainner to install.
The only reason I'm giving this product 4 stars (as opposed to 5) is because of the no instructions that the product came with--even the own manufacturer's website neglects to divulge that kind of (crucial) information! Had not been for previous reviewers on this website, I would have installed the antenna improperly (i.e., the blue cable).

Crutchfield Customer Review (What's this?)

Nice quality antenna. Leave it to Honda to try and come up with a "better idea" for an antenna connection.

Instructions could be clearer when it comes to hooking the harness to the factory harness. The blue wire clearly states power antenna lead. No power antenna, no need to connect....right? But on SUVs with a bulit in antenna amplifier in the rear of the vehicle (like a Honda Pilot or Subaru Outback), this blue wire is what turns on the antenna amplifier. Do you know if your vehicle has a rear antenna amplifier...I did not because it is not listed on the Master Sheet for my Pilot. When I had it intially hooked up, radio reception was horrible. I was ready to send it back. Called Customer Service and the first question they asked was about the blue wire being connected. I had to take the dashboard apart again to hook up the blue wires....kind of a pain. If you know this in advance....it would be nice to have it clearly labeled.

Blue wire on antenna lead

Written by: dubinski from Mukwonago, WI on November 17, 2008

Crutchfield Customer Review (What's this?)

I had poor reception on the radio. The antenna lead did not tell you it had to be hooked the the blue radio lead. I had to call back to Crutchfield and
speak to a "specialist". He than looked it up and said that it was to be hooked up to the blue lead on the radio. I had to again remove the unit to hook it up. I hate doing things twice. There should be something on the package telling you that it needs to be hooked up.

After looking at the reviews of this antenna connector there are more reviews just like mine, this should tell you something.

Other than this one problem there was no other issues installing the unit.
