I have a bunch of questions on the wiring part of the project...
First here are some info about my project:
- 1986 BMW 325e sedan
- M62b44NV out of a 1997 740i
- Bosch 474 ECU flashed to delete ews, etc...
I bought the car with the project 1/3 "complete". The engine was already in and it actually cranks and turns on. The previous owner never finish it and decided to sell.
The wiring adapter that the PO made to the e30 c101 only has two wires (pin7 ignition switch and pin18 starter)
Note: this ECU uses a single big plug.
Questions:
1- How do you get oil pressure, coolant temp, rpm signal to the cluster?
I know that this been a obd2 swap the temp sensor is different (4 pins) than the commonly use single pol brown top one used on s52/m50 swaps.
2- How should the battery charging system be connected?
Big wire from alternator to starter and from battery positive post to starter... Am i correct?
Thanks!
