Wiring harness question
I got a Pioneer Deh-6800MP HU from Crutchfield and got the harness for it to connect to HU wring. There is a orange wire for Illumination on supplied harness and the HU wiring has a tag saying ILL. Those I soldered together. Now there is another orange/white wire on harness that says "positive Dimmer" on it. I can't find the HU wire for that. Anyone know if that is or should be connected?? thanks.

thats the one youre supposed to connect. our illumination wire is positive, unless your harness also has a orange/black wire which is the negative dimmer. typically with pioneers you hook up the solid orange wire from the car side harness to the orange/white of the pioneer. if you look at the wiring diagram you'll see what i mean, the input of the pioneer illumination is supposed to be ground. if you leave it the way it is you run the risk of blowing your parkinglight fuse.

Harness don't have negative dimmer just positive and another orange one call Illumination. Cuz yeh of now I have the HU ILL wire connected to the wire on Honda harness that says Illumination.

Rep Power: 263 The two wires on the Honda harness are as follows:
Orange Illumination Wire: 12V whenver parking lights or headlights are turned on
Orange/White Pos Dimmer Wire: Variable voltage relative to dimmer switch on dash that controls intensity of gauge lighting, 12V when fully cranked but it goes down as light intensity is turned down
Between the two the illumination wire is the better wire to hook up to if you want to dim your deck's display.
The dimmer on the deck is designed to "dim" whenever the Illumination wire on the deck sees 12V.
Only potential issue here is if you like to have your parking lights (not headlights) on during the day when you're driving, as I do. If you hook it up like this you can't see your deck during the day.
So I used a relay as follows to take care of that problem:
85: 12V
86: (-) headlight wire (blue/red at headlight switch)
30: 12V
87: illumination wire on aftermarket deck
Hope this helps.
