I have a set of 40/20/40's I figured the wiring harness would be a pretty easy swap but then I came into a problem the problem is one of the wire cupplings are different. Can anyone let me know if the is an adapter? If not what all do I have to do to get the right wiring harness out of the old truck? Here is a picture of the two the round one is what came out of my truck the square one is what came with the new harness.Both have 8 prongs on the inside. My truck is a regular cab 97 and the donor truck is a 96. if that matters at all.
P.S. Sorry if the picture is a little blurry.
