I have a 91 civic std, I just recently stared an ls swap. I've been told by a couple of different people that all i need is and 88-91 civic/crx si engine harness?
If i was to do that, would it be easier to get the cabin harness as well and just plug and play? thank ahead for the help

 

you need to modify your stock harness with parts from the si harness. look up mpfi swap in the faq

 

i understand that i can do that, but i have a si the shell is just crap. would it be easier to just use that harness?
or even use the si cabin harness, and a da engine harness?

 

you can use the si engine harness if you also use the si cabin harness with it. you can't mix and match between models (std,si,etc) or chassis (ed,da).

 

truth. if your harness is messed up i say why not? just switch out the cabin harness and that will work too

 

sure if you have it, might as well use it.
