October_V Posted January 10, 2011 Share Posted January 10, 2011 1990 Comanche. I have 2 wires in the radio harness I can't ID. The blue with white stripe and the orange with black stripe. Any body know what these 2 are? I have the control head in and everything works just fine, I just hate not knowing what these are for. I do not have a power antenna. I can link a photo of these 2 wires later if needed. Image Not Found Link to comment Share on other sites More sharing options...
lostissues Posted January 10, 2011 Share Posted January 10, 2011 are these wires from the jeep or from the radio harness? after market the blue white would be power antenna or amp turn on (I always get them mixed up) and the orange black would probably be dimmer or illumination.

October_V Posted January 10, 2011 Author Share Posted January 10, 2011 These wires are from the Jeep wire harness, everything was cut and taped so I ordered a replacement dash harness plug to do the new in radio install proper and clean. I am inclined to agree with ur assesment of dimmer and power antenna. I'll have to dig into the dash again later and put these wires into the radio harness plug and see what happens but after I get more info. Link to comment Share on other sites More sharing options...
MJCARENA Posted January 11, 2011 Share Posted January 11, 2011 In the 88 Comanche electrical book,on pages 56 and 59 it shows that the blue/white is Dim Display Input on pin 11 and the orange /black is the Display Backlighting Lamps on pin 10. The link for this manual is on this site somewhere. Very good manual to have and again I thank whoever posted it. I found the link. Worth printing out and keep in your truck. viewtopic.php?f=9&t=12734&hilit=electrical+manual Link to comment Share on other sites More sharing options...
