Hey Vince! So this may only be a PSI harness configuration and like I said, John is always there for support. My issues are switched fan runs on start up, OBDII is not able to be read w a code reader or HP Tuners, check engine light does not come on momentarily upon start up, and the Tach is not reading a signal from the computer.
Sounds like a system meltdown right?
It's a ground and a resister issue and that's about it.
The car electrical system is currently is ground to the frame and the motor. To test it we ran a ground from the E38 computer to the battery. Also checked the pin outs:
OBDII Port:
POSITION 4 TO GROUND
POSITION 5 TO GROUND
POSITION 6 TO BLACK ECM CONNECTOR POSITION 28
POSITION 14 TO BLACK ECM CONNECTOR POSITION 27
POSITION 16 IS SWITCHED 12-VOLTS
Here's the Autometer Tach/resistor issue.
