Dash Harness - Factory Five Racing Mk3 Roadster Assembly Manual

6. Using a 87-93 harness, wire the black electric fan wire to the frame. It serves as the ground.
7. Connect the other electric fan wire to one of the dash toggle switches through the relay provided. The
fan is not needed all of the time. The 2-position toggle will serve as your on-off switch. If a
thermostat control is desired, you can pick one up at your local auto parts store.

1. The dash harness begins at the coil area and goes rearward to the large hole in the front of the driver's
side foot box.
2. The key to routing the dash harness is to start on the inside of the foot box and push the smaller items
through the large hole from the inside.
3. The connections for the coil, starter relay, and the connectors for the rest of the harness easily fit
through this hole and the big rubber grommet on the harness press fits into the laser cut hole.
4. Remove 4" of the tape covering the harness wires on the outside of the dash harness grommet.
5. Pull enough of the harness through the grommet so that the coil can still mount on the outside of the
¾" tubing next to the master cylinder. By doing this, the amount of visible wiring in the engine bay is
reduced.
6. Run the harness over the pedal box and through the large slot in the firewall.
