Repost: d15b6 with mpfi swap
This is a repost from the electrical section, apologies if this is improper etiquette .
I recently came into possession of a project 1991 dx wagon that has been "swapped" with a d15b6 with mpfi. I am confused as to the wiring that needs to be done. I have both the harness for the new engine and the harness from the original engine and was wondering what be best course of action would be. Which harness should I install and then begin splicing wires into? Additionally, are there any resources here or elsewhere that might allow me do some additional research? Thank you.
