newb. dme issues.

Hi all, I am new to the "I care and know about my car" community. My knowledge is limited and my abilities are even more so. Thanks for your expertise and your patience. Hopefully one day I can be of help as well. March 2014 I purchased my Hellrot 1995 BMW 318ti A US KOMP from a friend. It had a clean, un-abused history. Over the summer, the water pump started leaking, I had it repaired as soon as I could, but it managed to overheat. After the repair, all seemed well. About a month later she started running a little rough and over a day or so it got considerably worse. I parked her and got her towed to a shop. They told me the radiator had a leak, the fan worked itself so much that the motor burned out, needed a head gasket. There ended up being a few other things that needed to be replaced...temperature sensor, not sure what else. She was running fine for them for a few days, and then...she wouldn't. On a cold start, the temp gauge would be pegged hot, the tach wasn't reading right. Jiggle the wiring harness, and issues would change. Sometimes it'd start perfect, other times nothing. - So, before they began trying to trace wires, they told me all of this. And seemed very pessimistic about being able to find a new harness. Their conclusion is that the wiring (harness) is probably damaged due to the overheating and it'd be easier to replace. If that's what needs to happen, I agree. - I've been looking online for the right part (wiring harness/DME), and I can't be certain if I've found it (different part numbers and other acronyms that I don't know what they stand for). So I started looking for a service manual for part numbers and more clarity, and that was just as much if not more of a mess. Help! And thanks!
