Multi Function Switch ???

[Blakthorn]

Anyone have a working spare I can buy off them?
Or perhaps working GT Headlight/Fog Light switch?

Also I have a few questions, are the multi function switch compatible from 1987 to 1993?

Another question - The headlight wire is red and yellow which carries the current from the headlights and foglights - What does the red and black double wire right next to it do?

There is a difference in early and late aero fox MF switches (had a bud try and install a late model version into an early model - no workie). I think 87-89 use the same one and 90-93 use their own. Check with others to be sure (or check a resto site as this should be stated).

Good luck.

Any idea about the red and black wire on that switch?

The red and yellow, which is now the blue and red in that picture is for the headlights/fox lights - I need to know what the wires to the right of that does?

Anyone know?

Maybe one of the AutoZone diagrams will have the answer.

I think the two Red/blk wires are a continuation of the red/yellow wire. Each Red/blk wire is the output from the MF switch to the individual headlights (ergo there are two wires).

Good luck.
