I was swapping C1 to B10, that was fine. Then I swaped C2 to B12, and there was a wire already in B12. If somebody has any suggestions or a pic showing which wires to where to make sure I m counting the plugs right, that would be a big help.

BTW, I am doing the swap on a 91 HB Dx w/ A/C and MT.

I don't know if this helps or not, but here's a site with a good writeup on the wiring

You may have a wire at B12. I personally did. Some did some didn't. Just cut it off and wire the way its suggests. Not sure why some do and some don't truthfully though...

 

B12 on the DPFI is a white wire with a red stripe used for the "shift lock control unit" on automatics. It was probably included on some models because it doesn't make a difference if it's there or not.

I took a look at the schematic and there is not a connection on the MPFI ECU for the "shift lock control solenoid". I now wonder why the DPFI car needs this and the MPFI does not.
