I have power tow mirrors, i want to put them on this truck... is the wiring harness inside the door panel? or non existent...There is a cap over where the toggle switch would be on the door panel. If not i guess these are useless.

 

Have you popped the door panel off and checked? A lot of times vehicles come wired for all kinds of accessories even if that particular trim model doesn't come with them.

Then again, I honestly don't know.

 

The connector, if it is there will be located near the upper corner of the door panel near the A pillar - I think a four pin connector. If it is not there, that would be a major task, with realys and such to add.

 

on my 98 its a base model had door panel off only had speaker wires going to door
