Im looking to do power windows,locks and mirrors on my 96 civic dx which has none of the above. Now i already have complete doors off a 97 civic ex with mirrors and all. Now when going to wire it up can i juse use the 97 ex underdash harness so that everything is already prewired and all i have to do it plug and play??

Or what is the best and easiest way to wire in all the accesories in a manner that will be legit enough to also install keyless entry??
