Take the whole cooling system with rad & expansion tank too, & gearbox if its manual. For most everything else use the E34 M50 stuff as you probably already know, and of course get the E38 728i oil pickup tube (the correct one for your engine build date).
I need to start studying up. This is great news...1973 Bavaria

If you choose a ZHP engine then you'll need to have an MS43 DME tuned for it because I don't make harnesses for the MS45 DME. It's not so important which BMW Series the engine came from, but I recommend using a E46 or Z3 harness depending where you want to mount the DME. I don't have the part number for the 12-pin E39 X6011 connector so if you got a harness from an E39 I'd have to label those wires for you.

I've decided to begin offering the under-hood diagnostic port for the E36, for S54, M54, and M52TU. It will allow diagnosis of body control modules such as ABS. It will come complete with bracket & cap, and will be integrated with the adapter harness. Add $250 for this option.
I can sell it separately to those who have previously purchased an E36 adapter harness, but there will be wiring to do. If you want it I will include instructions.Last edited by Andrew325is; 02-06-2016, 01:36 PM.

Can this be added for existing customer cars?

I've been told the power wire for the fuel pump relay (the one with the fuse) isn't long enough to reach the B+ junction (at least on an E36) and the red power cable isn't long enough either. I now make the fuel pump relay power wire much longer with the new style fuse holder, and I'll be making the red power cable longer as well from now on. If you find yours aren't long enough you can cut the ring terminal off and crimp a butt terminal on to connect to another wire. For the fuel pump relay wire use 12 or 14 gauge wire. For the power cable use 10 gauge wire. Use heat-shrink terminals so they're sealed up good. I can send you a new red power cable instead if you'd like. Just let me know.
Alternatively you can connect them to a small battery junction block like this one, then connect it to the B+ junction with a battery cable like this one. They come in various lengths. That's the easiest solution.Last edited by Andrew325is; 02-16-2016, 12:26 PM.

Originally posted by Andrew325is View PostI've became aware of a potential issue with using the E34 M50 oil level sensor on S54, M54, and M52TU engines, so I recommend not installing that. So from now on I am omitting that connector on S54, M54, and M52TU adapter harnesses for E30 and E28 that have check control. The engine's original thermal oil level sensor should remain installed. The thermal oil level sensor includes an oil temperature sensor that the DME uses to monitor oil temperature. According to BMW, "The engine oil temperature is required for VANOS activation. It provides a more accurate indication of the engine temperature than the engine coolant temperature." So without the thermal oil level sensor installed VANOS may not function properly.
The adapters for older engines such as S50 will still include the E34 M50 oil level sensor connector if your model has check control.
Only the S54 uses the thermal oil level sensor for oil temp data, but I haven't been able to confirm whether or not the DME uses that data for VANOS activation.

S54 subs oil for coolant, seen this when logging. Never seen Ill effects when tuning of it doing this. Vanos still works. Potentially some background stuff going on im not aware of but again motors still make great power when running like this.

So i have acquired a e30. It has a s50b30us. Its is obd1. The person I got it from did such a hack job at wiring this car and cant make it run correctly and am afraid of damaging the motor. Wondering what i would need for wiring on this. Its a 1986 325es.
sent you a email.Last edited by dgg15; 03-22-2016, 01:48 PM.
