Hello everybody!I have a "96 316 m10 carburator e30 and i wanted to change it with m42,so i bought an engine,cooling system,trany,driveshaft and all the engine wiring.But i have a problem with connecting the engine c101 with the m10 one.I have red many threads and charts but i can't understand whitch cables do i need.I have pluged it in but when i put the ECU my cluster lights for oil,batery and brakes got ON,with no key on the ignition and the dashboard fuse blew up.I have looked the c101 and saw that Should i buy a new m40 car instalation or i 6 or 7 pins are missing(fuel pump,abs and so)Should i buy a new m40 car instalation or i can use the original one?
