i have recently swapped in a 1988 325is engine with harness and ecu into a 1987 325e chassis. upon turning the key, nothing happens. the is getting power, but not doing anything. the windows/sunroof/fuel pump are not working. I suspect it is the unloader relay since it is currently not wired in, i have been told the unloader relay is pin 15 on the 1988 325is C101, but have not found where to connect it to the 1987 325e chassis.
Also if someone could clarify the C104 wires and where to connect those, i would be grateful, i currently have the black (pin 1 i believe?) connected to the tach input, but nothing else. Thanks
