Quick Head unit wiring question.
 

I have an aftermarket wiring harness with:

1. Orange/white stripe says dimmer and
2. Solid Orange says illumination/dash

My JVC head unit has:

1. Orange/white wire

Which do I splice into? one or both? I'm thinking just the one that says illumination?

Thanks,

just use the illumination wire. Most cars don't have power going to the dimmer wire.

Thanks, I used the illumination one and it works. I ran into a different problem though.

What problem?

I was also wondering about the dimmer control.

Can you actually use the dimmer switch that controls the dash, to control the head unit dimmer?
