Auto to manual electical question

[88CReXin]

Hello good people. I need to get a dash and engine harness for my 91 hatch. Seeing how finding one for a manual is near impossilbe or expensive from where I come from I've decided to pick one up from a 90-91 4-door automatic instead. I was wondering what kind of modifications do I need to do to both the under dash and engine harness to work for a 5-speed. BTW the hatch is a dx model but I will be getting the donor harness from a mpfi if I can find one. Thanks

It will most likely be a Lx. I've seen very little Ex four doors around here. I plan on using Boomslangs dpfi to obd 1 mpfi conversion kit cause it has all the nessccary wires needed.

What pins did you have to eliminate?

Thanks for the help. I was just wondering is there any difference between an auto and a manual harness.

BTW I got lucky and found a complete harness out of a 89 Lx 4 door that is a 5 speed. For $40 I have to pull it myself. Hopefully I won't ruin anything. I'm getting it next week for sure
