Hello all, first time poster, been doing a lot of reading and working on this '90YJ 4.2 auto Sahara.
Most all of my questions have been answered by using Search and the FAQs. Thanks to all who have posted that stuff up. I've not found a single thing to ask that hasn't been covered till now.
I'm fixing the hack wiring job someone else did on the radio while waiting for all my LED instrument lights to come in. The wiring I have does not match to anything I've seen listed anywhere. It's a factory harness, as it's taped and wrapped right into the main harness. Looks much better than the hookups to the radio.
I'm pretty good with all this stuff, just need a little help if anyone else has come across this. Here's what I've got and what / how I determined what it is. You'll see the ? where I don't know what it is.
Brown = RF- verified by 9v test
White/Black = RF+ verified by 9v test
Brown/White = LF- verified by 9v test
Green/White = LF+ verified by 9v test
Orange/Black = instrument lighting, volts vary with dimmer
Pink (Orange?) = 12v+ battery constant
Purple/White = 12v+ switched ignition
? Blue/White = gets 12v+switched from the ignition, then when ign switched off, slowly drops off volts down to zero
? Black #2 = 12 ohm to gnd, no voltage (key on or off)
? Black #1 = Open. No ohm to gnd, no voltage (key on or off)
? White = Open. No ohm to gnd, no voltage (key on or off)
? Black/Yellow = Open. No ohm to gnd, no voltage (key on or off)
? Green = Open. No ohm to gnd, no voltage (key on or off)
I'm going to run my own chassis ground, since I don't see a good ground wire.
My big question is the last 4 open wires. I am suspecting these are for rear speakers, but there are none installed and I don't see these wires running under the door sills. Don't know if the Sahara came with rears in 1990.
If anyone can help with these unknown wires, I'd appreciate it. I'm headed out to solder and shrink the ones I know, at least that will get the radio working right.
Thanks for this and all the other posts / FAQs I've used over the last month or so... you guys know Jeeps like no other forum on the 'Net.
