I'm in the middle of swapping a B18a into my 1990 DX. The problem is, it was originally an automatic. So I'm converting to manual AND MPFI.

I've already followed the guides to convert auto -> manual, but now I need to do the mpfi wiring work. Can I use the original auto wiring harness and ignore the auto wires?

According to this: http://www.fourthgenhatch.net/mpfi.html pin B11 is wired to the shifter position switch, D4.

Since I'll be using a manual ECU, I'm assuming that the "shifter position switch" is a auto only thing and won't matter, but I need to make sure before I hack up the wiring.

ya use the orig harness and leave the auto plug alone it will work.

 

I figured as much, I'm just stupid when it comes to electrical work so I needed to make sure.

But you better be right, or I'll fly down to CA and kick your ***

 

i wouldnt have told you that if i my self didnt turn my old auto dpfi crx to a manual ls swaped crx.

 

I just completed the same thing with a 5spd & B18b into an automatic DX sedan.
