We just picked up a salvage unit with a complete b18c conversion, and I want to put it in my 97 Integra LS. Everything thing looks like it should be an easy swap, except the harness. Must I pull my complete dash to swap the harness that goes across firewall to fuse box? I am looking to save time from pulling unnecessary parts to complete the install. Help fast- I am halfway through. Next project...Built to the nuts H22 in '97 Civic H.B.
