165 to 730 question
I repined my harness and there is one thing I'm stuck on so I'm looking for feedback on how other people did this. It shows the D1 connecting to two different locations on the 730 ECM (both BD1 and BB6)?
Mike Davis' page shows this for the wiring conversion:
D1 (Sys GND) BD1
but also:
These signals can be brought in thru the harness on the MAF
wiring if you build an adaptor cable or splice into your MAF harness
plug. You MUST wire the adaptor or splice this way or risk an electrical
short:
BA4 (MAP +5v ref.) MAF pin B (165 ecm pin A11)
BB6 (MAP GND) MAF pin A (165 ecm pin D1)
GF15 (MAP Signal) MAF pin C (165 ecm pin B12)

Re: 165 to 730 question
Pins D1 and B6 in the '7730 ECM are both grounds. Those and pins B5, B9, and A12 are all tied together in the ECM via the ground plane.
