Yeah The only other time I have installed a stereo was on a 98 subaru so the wires are the same color making things easy.:)
Wiring n00b here, but you have to learn some time.

If you own an E30, you need one.

Now go kick its ass!

is there a way to check if the tach is getting a signal with a test light Still having problems with it I have swapped in two working SI boards and it is still not working.

[StereoInstaller1]

The tach signal is AC voltage, so you can't use a test light to test it.

Ok thanks again.
