Bought a new Stereo for the 95' Blazer. It ain't much, but it is a 7" touchscreen, bluetooth, etc. etc. (Overseas no-name model)

I am hand soldering all the wiring and I already have identified the speaker wiring and those are all soldered up to the new connector.

Have some questions on the other power and control wires that I could use the BF's help. Attached are 3 pictures, 1 which shows the wiring schematic for my truck, 1 shows the actual 5 wires in the truck (orange and yellow aren't tagged as as run out of label tape), and finally the new stereo wires. Obvious Black (Grnd) and +12V Constant are easy enough to figure out, but how do you think I should wire the remaining 3?

Any help and/or ideas are appreciated! Thanks!

 

Wire "PNL DIM" (grey) to the orange wire on your new radio (that one is hot when the lights are turned on; when the radio sees that power it will dim the screen and/or dim control button lights)

Don't worry about the brown one (it is the adjustable dimmer control ground circuit, I've never seen an aftermarket radio make use of that. just cap or tape it off)


You'll also probably want to ground out the pink park sensor wire on the new radio, this will bypass any lock that the radio might have that keeps you from getting into some settings or playing DVD's while driving (not that I condone such things :P)


You said remaining 3, from your description it sounds like you have the others figured out, what other wire are you referring to?

 

So I did figure out the two (2) 12V wires and the Ground is obvious, so I just needed the two remaing wires. Since I don't need the brown, all I needed was the Panel -Dimmed wire which you say goes to the Orange wire, but they don't even list the Orange wire on their wire schematic. Is this some sort of "Industry Standard" practice?

 

yes, precisely

 

Excellent. Thanks.
