Why spend extra money when I can dO it this way? But anyways any other ideas?

My switched wire must be dead or something cause it works when I hook it straight to a 12v source. And I just need to know the speaker wires for the dash sPeakers. Thanks for the others though

Thanks, I don't know how I overlooked that lol. Can I take a dmm to check the 12v switched

 

[Lowflyin 10+ year member]

I'm seeing other people say dark green is the switched, or is this just the newer ones

 

[>>SQL<< 10+ year member]

your right - that is for newer years

For 2002 up blazers the wiring is as follows:

Radio 12v orange+radio harness

Radio Ground black-radio harness

Radio Ignition dk. green+radio harness

Radio Illumination gray (dimmer)+radio harness

Factory Amp Turn-on N/A

Power Antenna N/A

LF Speaker +/- tan - gray+,- radio harness

RF Speaker +/- lt. green - dk. green+,- radio harness

LR Speaker +/- brown - yellow+,- radio harness

RR Speaker +/- dk. blue - lt. blue+,- radio harness

I must just have a problem with my 12v switched then. Weird that I took out the factory hu and 10 mins later tried this new one and doesn't work. Well thanks

K well the problem I had was that I was looking at the yellow wire for my right rear speaker. But I don't see another yellow one, what gives?
