Radio-Stereo Wiring / Engine Smoke in a 1990
 

Hey everyone,
I have a 1990 rx7 with stock radio wiring, and I accidentally bought an 88 pioneer stock stereo, and the wiring doesn't match up. Is there a write up on how to wire it up?
I would like to make my car back to all stock.
Another thing, is it normal for my NA 13b 2 rotor to smoke on cold start until it warms up?
I'm new to rotors, so all help is appreciated thanks a lot!!

I cant say much about the stereo but it is somewhat normal for it to smoke on start. It may be condensation burning off if it is not a thick cloud. If it at all resembles videos you see on youtube of blown coolant seals with exhaust pipes acting like smoke machines, then you know there's a problem.

Mine smokes a little and only at start up. Take what I say with a grain of salt though - I am new to the game as well and am diagnosing a cooling problem. Blown coolant seals haven't been completely ruled out yet.
