So I installed the Kenwood Excelon 493 about 2 weeks ago.
Had the wiring harness soldered in advance for a quick and easy quick swap from factory unit to the Kenwood unit.
Crutchfield wiring adapters, two of them total. One for the main power/speakers and all that, second one for the rear speakers of my Access Cab.
That's what I was expecting when I pulled my stock head unit, just two wires into the back of the factory stereo. To my surprise there are like 4 connectors going into the back of that SOB. So I've got extra connectors floating around in the back of my dash now that connect to god knows what.
I am thinking they are just unused floaters from some factory option that I did not have on my truck like premium sound or something along those lines.
However I noticed that my Kenwood isn't dimming with the illumination of the dash when I turn the dimmer down. Is one of the floating connectors holding a mystery illumination wire that I need to tap into?
Yeah, I wired my harness/adapter according to the instructions and diagram. I'm not a total retard when it comes to doing this stuff but this IS the first Toyota I've installed a stereo in after decades of owning Fords.
