is the harness for a 88 civic dx the same as the one for a 91 dx... did anything change

 

im prety sure there diffrent

 

Well there maybe a few different wires running, im pretty sure as well 91 had a few diff things. However they are both for a dual point set up and should both start the car in my opinion... as im still using the original 88 dx wire harness on ls vtec crx
