Save time and effort
Maybe you're incredibly busy. Maybe you just aren't handy with tools. Maybe you don't know that when you buy a car stereo from Crutchfield, we include a vehicle-specific wiring harness that you will have to connect to the wiring harness that comes with your car stereo. Crutchfield now offers a connection service for these harnesses, even for sophisticated wiring interfaces often required to retain important safety and entertainment features.
When you purchase our ReadyHarness service, we will open up your new car stereo, remove its wiring harness, then connect it — wire by wire — to the vehicle-specific harness (included with your package) that plugs into your vehicle's wiring. We will wire up every available connection that we can between the wiring interface and radio, and we will make connections for any steering wheel audio control adapter (sold separately) that might be needed — but keep in mind that you may have to make some further connections directly into your vehicle's wiring. The Crutchfield ReadyHarness is then packed back with your car stereo, so you'll be able to plug one end into the car stereo and the other into your vehicle.
We use a custom-tooled industrial crimping machine to ensure that your ReadyHarness will stand the test of time... and summertime temperatures inside your car! Our wiring pro consults the wiring diagrams for your car stereo and for your vehicle to make sure that every connection is correct. For simpler harnesses, we'll send you a set of custom-made connectors that are plugged together. Of course, we can't make connections from your car stereo to wires in your car that are sometimes needed (like certain connections for a steering wheel control adapter or a parking brake wire for a DVD receiver), so you may have to connect a few wires for more complex applications.
Why should I do this?
A Crutchfield ReadyHarness saves you significant time, effort, and potential heartache. In the past, you'd have to sit down with a crimping tool or soldering iron, match up the two harnesses wire by wire, according to function, and then make secure connections. Now, the ReadyHarness is ready to rock the minute you open up your new car stereo. And you'll avoid the pain of turning on your new radio only to find out that you've wired it incorrectly.
Please remember that it'll take some time for us to build your ReadyHarness, so plan on your new car stereo arriving at least a day later than usual.
Listen to our customers
"I am absolutely thrilled at finally getting the wiring harness and vehicle adapter connected properly. It certainly significantly reduces the installation time/effort. Not sure why you didn't start this years ago." — Bob M.
"Unless you do this often, why take the time and the chance that a connection is not correct? Then the time to figure out what wire is not working, etc.? You all fixed me up with one wiring harness. I plug into the radio and two plugs on the other end directly into the car. Swap a radio in 15 minutes. How cool is that?" — #crimpinainteasy
"Just wanted to drop you an email and say your adapter/stereo harness worked perfectly! I cut the installation time by at least 1.5 hours enlisting your service! Thanks again for a great job." — Tom L.
"AMAZING!! I was a Crutchfield guy back in the day, installing various car stereos in my cars. There always was chopping, wiring and a fair amount of brain surgery. I just installed a JVC CD player in my wife's Honda Accord in 15 minutes, thanks to your prewired loom and excellent instructions!
Thanks again for a painless process!!!" — Ethan S.
Does the prewiring option for the wiring harness come automatically when I purchase a car radio or do I somehow have to add that option into my cart?
If I remember correctly, it is an add-on. If you are referring to the plugs being connected and ready use out of the box. Small cost, but worth it to me.
