So installing a new HU in my vibe. The vibe has 2 wires an orange (illumination) and an orange/white (dimmer)......The new HU only has 1 orange/white wire and no orange wire. However it gets a little confusing, a sticker on the end of the wire says "illum". In the manual for the HU it says orange/white "illum" (dimmer control wire) - to car light control switch..............So im pretty sure the orange/white goes to the orange/white. The only thing that threw me off was the fact that it says "illum" on the wire.

Anyone wanna back me up and take the doubt out of my head? haha

 

orange/white to orange/white

 

Thats kinda what I figured, but it just seemed to make way to much sense to me haha
