Rear Harness - Factory Five Racing Mk4 Roadster Assembly Manual

manuals for the model year you are using are invaluable. They cost between $30-$55 ea. but are
well worth the money.

If you did not take the harness out of the car yourself, when connecting the plugs together, check
the wire colors going into and out of the plugs to make sure that they line up and are the same
color. The only plug that may not be the same color is the fuel tank harness. All other plugs that
go together should be matching in color and shape or they will not connect. Different color
plugs means you may have a different year harness than the rest of the harness that you have and
could cause complications later when trying to start the car.

If you decide not to use the Mustang chassis harness because there are so many extra wires, the
Factory Five chassis harness is a good alternative, it comes pre-loomed and labeled. It can also
be used in combination with the Mustang engine harness if running fuel injection.

Rear Harness

Run rear harness along left side of the frame trunk extensions. Use zip ties to hold the harness in place
for now.
