i was under the car today changing the fuel filter on my 87 t2 when I saw a yellow wire with a red tracer hanging down right next to it! Dangereous huh! weLL Its comming out of the little harness that has wires going to the oil pan it has a single connection on it but i can find anywhere or it to go. All the connections out of that harness are plugged in and dandy but does anyone have a clue what it goes to i dont have a manual handy
