Nothing...mine has a goofy connector about mid way through the part that goes to the alternator...I dont know if it is supposed to be there or not but I think I'm just going to take it out and fix that spot of the harness. Everything works it just looks bad and somebody has run a jumper around one of the wires. I'm just gonna take it apart and solder everything back without the goofy connector. I just need to figure out what wire runs the temp gauge as it is not hooked up and the wire seems to be mia... If you were wanting that harness..go for it..
