STEP 2.1: Installing the Ignition Feed Wire

All of the three wiring adaptations require that the instrument cluster be removed. I would recommend that you disconnect the battery before removing the unit to prevent any problems that may occur.

To remove the instrument cluster, proceed as follows:

1. Remove the 3 Torx screws on the lower steering wheel shroud, unclip the lower shroud from the top shroud and remove (it is made much easier by pulling the steering column fully out, and leaving the adjustment lever loose to be moved around whilst removing the shroud).
2. Remove the 2 Torx screws keeping the upper shroud on; they are high up towards the column stalks. Remove the shroud.
3. Remove the 2 Pozidrive screws securing the bottom of the instrument panel on. Remove the cloth trim that covers the gap when the steering column is at its extremist positions.
4. Remove the 2 Torx screws securing the top of the instrument cluster in place, on the lip of the dashboard.
5. Adjust the steering column so it is at its most out and lowest position; lock it in place.
6. Carefully pull the black trim “blade” at the top of the instrument cluster and use it to lever out the cluster; when you can, undo the connector at the back by pushing in the tab and pushing the red lever to the other side.
7. Manoeuvre the instrument cluster away from the dash, paying particular attention to the bottom lugs and the wiring on the steering column.

Now, you need to insert a pin and wire into the Pin 4 location of the power ISO connector. One way of doing this is to buy the pins from an electronics firm, solder a wire on, and insert into the connector (removing the central yellow bar to allow pin movement), or to buy an ISO extension lead (PC2-36-4) from an Autoleads stockist (e.g. Halfords). That way, you can plug the existing loom in without modifying it at all, and simply cut the wire on the extension. These retail for about £15.

The wire in Pin 4 needs to be the switched output of your time delay circuit. See here for wiring details.
