buddy of mine has a 2007 Expedition, he has a new head unit and speakers. Were trying to find the amp turn on and dont know what wire it is. I dont know if anybody will be able to help, but if someone has a wireng diagram that would be great.

Thanks
scott

 

uhh remote amp wire.. is blue i believe?

 

yea its blue

 

yeah I know that. It came stock with an amp and we dont know which wire it is. We want to use the stock amp, wich wire turns on the amp. Thats why I would like a wiring diagram. Sorry didnt explain well enough

 

the remote amp wire (blue) runs into the headunit and only powers the amp on AFTER the key is turned, hence the amp is off when the key is out (preventing battery drainage)

sorry i dont have a wiring diagram

 

Yes I know that. This is not an aftermarket amp, it is the stock amp from the factory. Dont know the location or the remote turn on.

 

So you want to use the factory amp with an aftermarket headunit?

 

yeah. He does I know it would be better to get an amp and wire everything to the amp. He doesnt want to spend the time doing it, and the money. so we need the wire that is the factory amp turn on so we can use the blue amp turn on from the new harness.

 

I'm not sure it works that way. Did the factory radio have two plugs? I'm looking at the wiring diagram right now.

 

yes two plugs. Would you be able to post that?

 

If you can't see the wires, let me know.

 

If that's the case, they'll need an adapter from the new stereo to the OEM amp.
Don't believe it be as easy as just connecting a turn on wire from the stereo to the OEM amp.
Not to mention, they'll need to determine which wires (at the stereo side of the OEM amp) from the stereo connect to which wires at the OEM plug to get the audio signal into the amp. Unless they already have an OEM to aftermarket wiring harness.

I wouldn't recommend this method myself, I'd bypass the OEM amp & let the stereo power the speakers directly.

 

Also, did he have the audiophile system, nav system or thx system?

 

Would it be that wire going to the smart junction box?? What color wire is that(blue/red) ?

 

We have the aftermarket wiring harness.

Im not sure.

 

Ok. So you have the aftermarket amp integration harness? I'll keep looking for amp turn on.

Also, it's important what factory radio he had as wiring colors are different for different stereo and audio systems.

 

Yes we have the integration harness. Im not sure on the stereo system he has.

 

Ok. Well I'll just assume the audiophile one.

I would use the Violet/Red wire coming from the Audio Control Module.

 

Sweet. Thank you. Would you be able to tell for the other two if its not the audiophile system?

 

It's waaaayyyy more complicated if he has either of the other two systems. Navigation should be pretty obvious and if he removed it, he's an idiot. The THX system should be obvious too because it had special speakers and whatnot. The audiophile is the "basic" sound system for the Expedition.

 

Is that behind the dash?? (kinda look like it) or under the center console?

 

Big picture time. This should show you.

 

thanks tyler. He didnt have the nav in it. Is that Audio Control Module in the dash or console??

 

It looks like it's in the dash in the PDF, but I can't really tell.

 

I think it is. Well give this a try tomarrow.
Thanks again tyler
