yes. there are a few differences, the connecters around the tstat housing will have to be spliced in. also the hook up for your reverse lights might be different, but again thats only two wires, easy fix.

thats about it. everything else should be the same.

what conectors on the T stat housing are different? I dont have AC, so the blue on on the bottom is out, is the temp gauge, ecu temp signal, and other one that i cant remmeber the same?
