i'm doing an ls swap on my 90 civic dx. i hve the wire harness from the integra. can i use that harness or do i have to modify the civic harness?

no stick with civic harness. what year is the integra motor? if it is obd1 you need to get a harness from rywire or boomslang to convert the harness...you will also need a few other things such as a 4 wire o2, obd1 dizzy and a few other things

i agree can never go wrong with rywire

my car is done. ls in a 90civic sedan. love the power (want more).my problem is that the car idle goes up and down, even after it's warmed up.i plan on swaping the integra suspension over to the civic also.i allready changed the front knuckles w/ bigger brakes.and the sway bar.
i need an exhaust setup i'm still runnng on the civic exh.so i know it's being choked.was thinking of putting the integra ex. on until i can afford another system.

4d00rs where are you located?
