thanks in advance -Lj

 

can somebody please help? or is it that no one here has a clue about it?

 

Have you double-checked all the wiring? What info did you use to wire the head unit up?

 

Man, this is like the 1000th thread about installing a stereo and the car not working. This is why I used a harness adapter!

 

well i used the sony wiring diagram and bought the harness adaptor for the car... i did everything pretty much by the book and now i dont know wtf is goin on, ill double check it again... but does anyone have some sort of explanation for this... c'mon just refer to me as some dumbass... i dont care i just want everything worker properly, cuz honestly im new at this and i wanna learn it right. and i know theres a **** load of people that know whats up, im makin my way to get to where you guys are at intellectually i love my car, its all about that 2 rotor motor... shiet... thanks!!!

 

Personally I see no need for adaptor harnesses. I didn't need one and my stereo works fine. Matching the head unit's bare wires to the factory plugs (using a wiring diagam), crimping on spade connectors, and plugging it all in was a ten minute job.

I'd get a wiring diagram and check that the harness is wired right. Specifically check the head unit's illumination wire (since switching on the lights causes the problem). It should be connected to the red wire with a black stripe on the 3-pin plug.

 

ok yeah i was wondering why there was no illumination wire from the cars harness... but what do you mean by it should be connected to the red wire with a black stripe on the 3-pin plug??? what has a 3-pin plug?

 

There is an illumination wire. The stock head unit's harness has several plugs, one of which is a 3-pin. Look for the black/red wire on this plug.

 

oh ic ok i think i understand, im bout to crash but ill check first thing in the morning and ill let you know... thanks

 

Yeah, and having worked in the electronics field for over 14 years, I would agree. But sometimes I just like to take the easy way out. For the novice, I recommend the harness adapter.

 

I'll be sure to buy an adapter then.

 

Unhook the factory amps if you have any... they are crap and can frig your cd player if not hooked up properly...

 

Yeah right..

 

so your tellin me that my 90 vert comes with factory amplifiers?
whoa! thats news to me? can you tell me where theyre located?
also right after i hooked up the head unit for some reason the speakers in the headrest and also the rear speakers will not work i hope i didnt short mess anything up or shorted anything...

 

The stock stereos in all FC's had external amps. See the FSM for locations and schematics.

 

are you talkin bout the ae processing unit? and i dont mean to sound like a total newb but whats FSM?

 

No, that's different. The speakers had external power amps. The FSM is the Factory Service Manual, which you can download free from www.iluvmyrx7.com. Stereo info is in the Body Electrical and Wiring Diagrams chapters.

 

I think the amps are under the speakers in the rear strut towers and there's also one directly under the glove box. That's everything I know or want to know about radios/speakers etc. Get a Sony Walkman. humor

 

whats a walkman man? sarcasm

ok now that i got all that sorted out when i turn my parking lights on the radio turns off then turns back on, then when i turn my headlights on it does the same thing... what you think is goin on cuz im stumped...
