Help with radio wiring colors for ‘98 1500

[Eric Dukes]

Help. Anyone have a radio wiring schematic for the 98 1500. Can’t find the wires for the radio in the Haynes manual and the wires are faded to where it’s hard to tell which is which color.

I'm assuming you're installing an aftermarket radio? Is the factory radio connector already hacked off? If not, I'd recommend just buying the appropriate harness adapter and wiring to that. They'll provide you with a wiring diagram.

If it is, you might be able to find the pinout and/or wire colors in the '98 factory service manuals. You can download them here for free.

1st choice, stock unmolested harness? Go with adapter plug, gm connector to iso standard plug for aftermarket radio. GM plug cut off, missing. Get the service manual has wiring diagrams. Wire faded, use some 409, or mineral spirits, bring color to life.

Plug is gone. I didn’t realize mineral spirit would bring the color back.

After several hours of using a test light to find which wires are which and ohm meter to figure out which speaker wire went where and soldering on a new factory harness with heat shrink I now have a working radio in the 98. Thank you all for your help!
