Sorry if this sounds a little confusing. I am a learning amateur but I have a 1994 F150 XLT Flareside.

It is a Mark III edition and it has a light panel on the ceiling. It has one switch to turn on the light, one to open the power sliding rear window and it has another switch that my friend says is an auxiliary/extra switch that currently does nothing (it says 'ACC').

Does anyone know how to utilize this auxiliary switch? I don't know much about wiring.



Thanks

 

In case you were not aware, "Mark III" is not a factory option kit. That is an aftermarket conversion done by a conversion company.
