thanks i thouhgt so but wasn't sure. I think It should have one wire hook up as well. I just bought the truck and trying to fix all the little things that are wrong with it. I found two connectors that not hooked up kind of by the alternator, one is a one wire hookup and the other is a two wire. I think the one wire is for the oil pressure and the two wire might be for the fan heater/ac fan speed, because the fan only works on the highest setting not any of the other settings. Anybody know for sure? Serenity is Awsome, Sobriety is moderationfor me!!
