clearance lights

According to the wiring diagram, the lights all connect from the passenger roof then links to the others ending at the one on the drivers side and then splices on the wire marked l7 18bk/yl which is the same wire on radio main grey connector.

I can't see that going to the radio wire when it comes down the pillar right there are the head light switch where it really needs to be installed.

Correct It does travel down the pillar. What I was saying was that yellow black wire is the same wire going to the radio. The actual splice is close to the switch.

What I meant was it should have it's own slot on the head light sw. instead of a splice into the radio wire. That wire dims the lights in the digital radio when they are turned on. I don't see how they could power the clearance lights.
