I need to try a new temp sensor on the 86 and I dont remember which one Allens harness needs. I have been waiting on a call back from Allen for a couple of days and just want to buy one to see if it solves my problems. It isnt a factory 98 camaro sender. The factory one is a 3 prong and the harness is for a 2 prong. Anybody know what the right one is?
