so im very new to this, i have a 1987 e30, an m50b25 engine with harness engine mounts shift bracket brake booster and other stuff im pretty sure i have everything needed to swap my car because my cousin gave me all his old stuff from his swap...anyways he told me i need to modify my wiring?
not sure exactly what he means by that but if anyone can give me advice or help me out it would be much appreciated, thanks in advance for your help! -Ray
