Hey guys im 19 and just recently got a haltech for my S5. The issue is im very illiterate when it comes to wiring so i bought a pre-terminated harness so i wouldy have to do any of the work just to later find out i need to terminate the interior harness myself. Does anyone know how i can wire up the clutch and brake pedal switch? is it just a 5v power and an AVI connection? I also do not know how to wire up the AC switch button since i am going to keep AC and i saw an ac switch connection on the wiring diagram.

 

Well for haltech you don't really need the clutch and brake pedal switch. A/C would connect to an input to the haltech from a swtich. Then that would make the haltech output to a relay which triggers the A/C. Google "Haltech how to wire a rotary" for the specific rotary quirks. Everything else is the same as any other haltech install you find. There's also people you could send your flying lead to and have it converted into a propper harness.
