The loom that comes from the ignition switch has 2 connectors just under the steering column. The turbo timer plugs in between these connectors. Just look for the ones that match the turbo timer connectors.
If your looking for a place to mount the control module ( the one with the buttons on it) it fits perfectly in that strange space next to the hazard and demistor switch.
I just installed the timer!! Does the thing need to be programmed or just select the time and that's it?? Reason I ask is because it won't work!! All I've done is earthed it
