To get dash to work was turning into a bit of a problem, all the sensors like water temp, oil light, alternator light are wired to the factory e46 DME plus theres the tacho. . To get around the problem I decided to still run the 4 cylinder DME, I removed anything that wasn't going to be used , leaving only the crank trigger, water sensor, oil pressure, alternator light and power supply. I made an extra bracket to mount the crank trigger at the front of the motor and pick up off the M60 crank pulley.
I then started to wire in the M60 DMe and trans , ecu. It still have to mount the computers and wire in the P/S button, reverse lights, Park/ neutral starter lock out. And then move on to suspension and brakes
But in the mean time it runs and can be driven.
