Hi everybody

Im soooo confused... i cannot work out how the wire map for the radio is on my MR2 Turbo 1991..

Right now it is fitted with an original radio/tape-player, i want to change it to another headunit, but i cannot work out the wire map on the car..

What color is B+, ACC, GND, Antenna, AMP etc.

I am not novice in electronics.. but i keed on measuring trying to find
ground, B+ etc. but this time im about to give up...

My car is fitted with original sub-amp and amp for front/rear left/right speakers.. can i feed the original amp whit a line signal from my new headunit?

Try and get a wiring harness for your cd player and car model. This should make it nice and simple. Tell me what kind of cd player you have and I might be able to get you a pretty good deal. I have a friend that works for a company that makes them.

Hi

Thanks for the answer

I have the wire map for my new cd player...

And i have the MR2 Electrical Wiring Diagram, but it is only for the European MR2 SW20 (3SGE), and the wire colors do not match my model (US SW22 3SGTE) at least not on the radio part..
the turn signal, door lock etc. is the same.. just not the radio part
:(

So what i need is the wire map for the US SW22 3SGTE model..
- just the radio part ;)

You are my god ;)

Thanx.. allthoug.. I cannot use the cars original amplifier.. the input signal is something i have never seen before??

I understand hi-input signal from speakers.. and line signal from phono.. but that?? hmm.


Anyway, it helped me a lot ;)

Thanx again

Check out MRQ's sticky in the MR2 forum sometime. Helps out on a lot of those awkward questions. The entire Toyota BGB is in there.... which is where those diagrams came out of.
