USA-built Golf/GTIThis covers the 1985-1989 Golf and GTI built in the USA ONLY.Which Electrical System do I have? The fuse and relay boxes on these cars have wires connected directly to the back of them, so the wire colors for each fuse and relay pin are given. Also, the pin numbers on the face of the relay and fuse panels are given. When the same number is used twice, that is because each pin shares the same wire. |
