  • SPDT relay
  • Plug with 5 attached wires (red/white/black/blue/green)
  • Instruction/Application sheet

Product Research


Overview: The SPDT (single-pole, double throw) relay is a switch controlled by a voltage input instead of a mechanical action. By sending current through the relay, you can turn a device on or off without touching the device. The relay consists of two parts: the relay, which includes a 5-blade socket, and the 5-blade plug with 5 wires. It has a capacity for up to 30 Amps.

Typical Applications:

  • Relay Turn-On: for turning on/off high-current devices such as multiple amplifiers or neon lights
  • Relay Turn-Off: for turning off or disabling a device such as a vehicle's starter system (in conjunction with a security system)
  • Remote Trunk Release: for remote control opening of a vehicle trunk (in conjunction with a security system--requires existing power-assisted trunk release)
  • Power Door Lock System: for remote control locking/unlocking of vehicle doors (in conjunction with a security system and aftermarket power door locks)

Wiring Considerations: Installation of this relay requires soldering of the connections. Installation of a 30-amp fuse and fuse holder may be required near the battery connection.

This product is required as it replaces the warning tones which are programmed into the OEM unit being replaced.

Pros: simple install.

Metra E-5000 Relay

Written By zbee062, Anderson, SC on Tuesday, July 22, 2014

Crutchfield Customer Review (What's this?)

This is installed in combination with a GMOS-04 adapter, a DNX890HD in a 2008 Corvette. Apparently it can be eliminated if the GMOS-04 cable is by passed (with Corvettes of certain years ), but I elected to include it and followed the instructions provided.

Pros: Instructions were clear and installation was easy. Would give 5 stars except I had no way of knowing 100% that the relay worked. Everything worked that was associated with the cable including sound quality, so I assume that it did work.

Cons: None

Works as adverstised

Written By PM, Baldwinsville, NY on Wednesday, April 23, 2014

Crutchfield Customer Review (What's this?)

This relay was required. Instructions are minimal. I am not an electrician and w/o Crutchfield advisor, I would not have know where to connect the wires. Would have been very helpful to include more specific wiring instructions with the MasterSheet sent with the NAV/Radio I bought.

Pros: Works

Cons: A lot of wires. felt install instructions needed to be better.

Written By Bill, Los Angeles on Tuesday, October 29, 2013

Crutchfield Customer Review (What's this?)

Great product and very easy to install. I would of liked to see the relay be able to be connected to the radio. With all the adapters the harness became massive and cumbersome to install.

Pros: Went in very quickly

Cons: Need more documentation to install without pro help.

Good product

Crutchfield Customer Review (What's this?)

I was replacing a lightening fired unity in a 2003 Chrysler Town and Country with the Infinity system. Installing the relay was not really that difficult or complicated, except the instructions were confusing and not completely correct. The Crutchfield Technical support helped me get it properly installed. They were a big help.

Crutchfield Customer Review (What's this?)

Initially I hooked-up this relay, but din't like how I would have to struggle with
finding a home for it.
It works, but I chose to do without.
I can't hear it anyway when I have music on.

That's It

Crutchfield Customer Review (What's this?)

Well theres four wires, and i only needed two both turn signal sounds work and
i would recommend this to anybody who just wants to keep all the factory car
sounds while having an aftermarket radio. It was very easy an no problem with
product so far.

Worked Fine

Installed in a 2001 Chrysler Town and Country with the Infinity sound system. I had to get instructions to connect the amp power lead (pass side kick panel).

Works great.

Not for '89 Audio 100 without Bose

Written By Art, Easton, PA on Monday, February 09, 2009

Crutchfield Customer Review (What's this?)

Solution where each speaker has its own amp, this solution did not work. Product was returned. Sound muffled and noice from engin could be heard.
Crutfield should consider other options.

Multi purpose

Written By Paul, Stamford, CT on Monday, June 30, 2008

I had a problem in my car. i had a cap, jl 1000/1 and a TMA320.4 running off the same REM line from my head unit. It simply wasnt enough power to startup all of the components. I put this relay in to put more power into the amps to start them up. Its a great thing and works flawlessly
