I would go to a reputable audio guy make friends with them and get the work done right the first time. them.

 

x3 on Crutchfield
x2 on Alpine
x3 on nothing else needed. I'm 3 years in with my set up w/ no problems.

To my knowledge, w/out the can-bus whatever relay BS thingy the only thing you lose is your radio face will not dim with the interior lights. And who the hell cares.

This whole setup is ran off an Alpine headunit with no bs interface, just a straight up wiring harness like putting it in a 91 civic.

 

Nice setup

 

Thanks man. Created from Crutchfield and craigslist and some paint haha

 

The adapter is not needed but here's some details of what it's about, so you can decide for yourself if you need it or not.

The CANBUS controls the following signals sent to the radio.

- ACC/Ignition switch. If you don't get the PAC interface, then you can just as easily run a wire from the Cigarette lighter to the IGN wire of your aftermarket radio, so the radio turns on/off with your ignition.

- Speed Information. This is needed if you get an aftermarket radio which has navigation, since a lot of better navigation systems use a speed pulse signal from the vehicle, to know the exact speed you are traveling. I believe the PAC interface will convert the CAN BUS speed information, to an analog speed pulse wire, that can then be connected to a Navigation radio which uses a speed pulse.

- Lights On/Off/Dim/Day/Night mode operation. If you can live without this, then you don't need a PAC converter. The Pac will do a Can bus to analog wire conversion for this function.

- Park/Gear Shift Status. You won't need this, but this is how the OEM radios know that you're moving or not, and how they disable certain functions. If you've heard of the "lock pick", this is the information on the CAN BUS that the lock pick alters, so that you can use certain functions while the vehicle is in motion.

- Reverse Status. This is the information the OEM radios receive off the Can bus, so that it will automatically switch to a rear camera view when you are backing up. I'm not sure if the PAC has some kind of analog converter wire for this, but you would only be interested in this, if you bought a radio which has a backup camera function.

 

been thinking about changing my stock radio my question is if you dont use the PAC's C2R-CHY4 harness and jump off the cigarette lighter does it affect your warranty ?

 

Sure it does. If your mod causes some kind of electrical short which causes some computer module to malfunction, or if your cigarette lighter stops working......then these things obviously wouldn't be covered under warranty.

Any changes you make effect the warranty, but the change must be related to the failure for it not to be covered under the warranty. Even using the PAC, that will effect your warranty also.

 

So how about we say it like this you need the special harness if you get a navi fancy LCD with back up camera and the works head unit , you don't need it if you get one that just plays music and charge you phone
