I tried to install an after market radio earlier this year, and it worked fine with a Scosche? accessory that helped supply CAN power, but it eventually killed my battery, so I uninstalled it. I tried again a few months after, this time direct set-up, and I 'decided' to hit the radio with a 12V current and fried it. I just recently bought another radio, started hooking it up today, and of course the wiring harness was wrong. I have no idea what to do anymore.... I'm feeling hopeless. Any help?

Dodge Dakota 2005 w/ Infinity System.

 

I had a aftermarket radio, I used the 12v Outlet under the dash, and had it set to IGN Power so the radio turned off with the truck. No issues or anything wired that way.

 

as mentioned by Reject, the best way without spending a bunch of money on the wiring harness... is to tap into the 12v plug on bottom side of the dash, thats what I've done with all my setups, i had one of the nice wiring harnesses hooked up when I had my comp system in and it fried the dash. killed all power in the dash and everything. needless to say that after than, and the 5+ hrs it took rewiring the entire dash...... i'll never go back to factory integration.

 

Damn, I've heard newer vehicles were a PIA when it comes to the stereo being integrated. Didn't realize it was like this. Guess the days of buying a $20 adapter and poping something in the dash are over.

 

My 12V power outlet is always hot, I don't know how to change it to accessory, any advice?

 

Now I'm confused, are we talking about the lighter outlet, or the code scanner system bellow the brake release and hood release?

 

The lighter/12 v power outlet. I can't see tapping into the OBDII wiring doing anything positive.

 

My 12v is always running hot, I don't know how to change it to ACC

 

You need to change the position of fuse # 22. It controls the power outlet to either always hot, or on with the key.

 

Oh my god. I can't believe this. I am about to cry from happiness. Thank you so much. I just thought I sucked. You always come through! Thank you again.
