Long story short, this was on my early CIS 8v manual swapped. I didn't do the swap. so I'm not familiar with throttle body, I think the harness is for cruise control? anyways, works fine. switch works fine also. my golf didn't use the harness or switch. harness is cracked but the pins are still good. overall the throttle body works and looks great. 60 bucks. you pay shipping.
