ECM/MAF wiring
A little background info. I rewired my 96 ecm from auto to manual. I got the swap running but I am getting the p0100 code. So i checked to make sure I was getting 5v at pin 1. I am not. I am getting 5v at pin 2 or 3 or 4. i dont remember which one. Would be an indicator that i have the maf pins mixed up at the ecm?

There is a snap shot of my ewd. Would +b need the 5v?

B+ (W-L) is the 12v lead from the EFI relay.
The document shows the wiring configuration for the pins. Just match it to your ECM. I am not sure what ECM your are running or I would help you out.
It says that
1= B+
2= F8 (auto), B2 (manual)
3= F7 (auto), B10 (manual)
4= ground
5=F18 (auto), B8(manual)
use a meter and check for continuity for those pins on your MAF to he pin on your ECM

I had that issue too but it turned out to be the C plug itself. It was moving around enough to kill the engine and throw the MAF code. Sometime it would throw the Coolant temp as well. I end up just taping some elec. tape to the side of the connector so it would be more snug. NO more problems.
