    hey where can i connect my remote turn on wire (blue) for my amp since i am keeping my factory 6 disc changer. i have a 2002 accord ex. In the past i have just connected it to the power radio antenna wire but thats not an option. thank you

    Cruz, technically you could connect your remote turn on wire to the radio switched 12v+ wire (white/red). That way your amplifier is on whenever the car is on and off your amplifier when your car is off. Just make sure to run an in-line 1-amp fuse on the remote turn on. Hope this helps. Good Luck.

    Hi, I have a 2002 Honda Accord Coupe and had purchased an Eclipse AVN5435. The headunit comes with the steering wheel adapter, and I’ll need to purchase the PAC-ECL to make it work, but I was wondering where I’d be able to find the wires for the steering wheel controls? Will I need to do some digging or is it relatively easy?

    I just bought a Pioneer DEH-P6200BT and have it installed just fine with an aftermarket wiring harness. However, I would still like to use my OEM steering wheel audio control (vol up/down & track fwd) but don’t know which wires to connect thru the harnesses. Any/all help is greatly appreciated.

    MrBback, you will need a steering wheel control adapter to keep your factory steering wheel controls:

    Dave, you will need an automotive auxiliary input adapter. This adapter will allow you to input any mp3 player or portable music player into your factory radio. This is the easiest and most cost effective way to add an audio input into your factory stereo. Here is the adapter you will need:
