Alright I've got a few questions here. Okay, now I've already gotten about 4 wires already figured out and hooked up. They were luckily the same color i.e.: oil pressure switch, alternator, starter, and the coil. What other wires do I need to hook up besides the coolant temp., and which wires would it be on my '84 318i? I see that the '89 735i wires are either brown and red, brown and violet, or brown and....green I believe it is. Also, since my car never came with an O2 sensor that was pre-heated, and the 735i's O2 sensor is does this mean that I will have to figure out some way to hook that part up, or do I just not worry about it being pre-heated?
EDIT: Looked at my diagrams again and noticed that all wires for the O2 sensor either go to the MCU or the fuel pump relay. So, that would indeed mean that I don't have to do any wiring for it, correct?
By the way I DO have wiring diagrams, but they of course are not always what they should be. For example the diagrams I've got on the 735i do not even show the oil pressure switch on it. Hopefully someone can help me out here. Thanks in advance.
