Good afternoon,

I attached a wiring diagram for you to view.

Do you have a test light or voltmeter to do some testing?

We need to some tests to see why there is no power.

Okay, did you check the ignition fuse for power on both sides? This is a power test, not visual.

If there is not power to the light green, then either the fuse is bad or wiring between the fuse box and the relay.

Hey, I just want to update you. I had put this project on a pause. last week I manage to get the problem sorted out, and I would like to thank you very much. The connection at this plug was corroded under the dash near the steering column.
