So I sold my harness to help buy the haltech and a friend was nice enough to give me a spare.

From searching is seems the s4 harness only has three wires. The S5 has five. Four blue and one black. The black wire seemed to plug into the other connector. mine was pulled out and the terminal was too big to fit in the plug it came with. So I got the cruise control harness, but I don't know where the black wire goes.

Could anyone post a picture of where it should go, or tell me which pin hole?
