35 Dollars Posted June 27, 2012 Share Posted June 27, 2012 I installed a 1990 4.0L in my truck, and I just want to make sure that the wiring in the bulkhead connectors have the same color coding, and they run the same things. Does anyone have an interior-view bulkhead connector diagram for a 1986 Comanche? I have one for a 1990 Cherokee, but I seriously doubt they're the same. This is what I've figured out so far based on the Cherokee (if it says Cherokee - then it didn't match, somehow (it was 4 years ago)): (the MJ doesn't have A/C) GRAY/blk - Left Turn Signal - A1 LT GREEN/blk - Wiper Park - A3 BLUE - Parking Lamps - B1 VIOLET/wht - Washer Pump - B2 BLUE/wht - Wiper High Speed - B3 YELLOW/blk - 4WD Switch? (1990 Cherokee) - B5 YELLOW - Coil Positive - B6 YELLOW/blk - 4WD Switch - C2 GREEN/wht - Ignition - Tachometer - C3 BROWN/wht - Backup Lights (1990 Cherokee) - C5 LT BLUE - Oil Pressure (1990 Cherokee) - C6 RED/wht - Battery - D1 VIOLET - Coolant Temperature - D2 RED/wht -Battery - D4 LT GREEN - Headlight Lo-Beams (1990 Cherokee) - D5 RED (thick) - Battery - E1 GRAY - Horn - E2 WHITE - Headlight Hi-Beams (1990 Cherokee) - E4 ORANGE/blk - Blower Motor (1990 Cherokee) - E5 BROWN - Right Turn Signal - F2 BLACK/wht - Brake Warning - F3 BROWN (thick) - Power Steering Switch? (1990 Cherokee) - F4 GRAY/red - Brake Valve? (WTF?) - F5 VIOLET/wht - Washer Fluid Level? (1990 Cherokee) - F6 LT GREEN/blk - Fog Lamp Relay? (1990 Cherokee) - G1 TAN/grn - Alternator/Battery Indicator - G2 WHITE/blk - Wiper Low Speed - G3 BLACK (x2) - Ground - G4 TAN/blk - AC Request? (1990 Cherokee) - G5 ORANGE - Choke Heater Relay? (1990 Cherokee) - G6 LT GREEN - AC Select - H1 GREEN - Starter Relay - H2 TAN/blk - Wiper Park - H3 GREEN/blk - AC Low Pressure? (1990 Cherokee) - H4 VIOLET/or - Rear Washer Pump? (1990 Cherokee) - H5 WHITE/grn - Washer Fluid Level? (1990 Cherokee) - H6 I am having trouble with getting any part of the interior to work: like the interior lights, instrument cluster, etc. Any advice you fellas can give me would be greatly appreciated. It's been four years since I bought 35 Dollars, and worked on it, and I would like to get her drivable. Thanks, Ron. Link to comment Share on other sites More sharing options...
sloride Posted June 28, 2012 Share Posted June 28, 2012 I have electrical diagram for a 1988 Comanche if that would help. I could scan it in and send that to you. It won't be before Friday that I can do that. Link to comment Share on other sites More sharing options...

35 Dollars Posted July 6, 2012 Author Share Posted July 6, 2012 Still looking for this diagram if anyone has it.... Sorry, Sloride, but I looked through all of those files, and they didn't have what I need. Below is a link to a similar diagram to what I'm looking for, but this one is for the underhood connector for a YJ - I'm looking for a Comanche 1986-1990: http://www.jeepforum.com/forum/attachme ... lkhead.gif Sorry about the link being from a different site, but what can I do.

DREDnot Posted July 8, 2012 Share Posted July 8, 2012 Are you talking about the C100 connector(engine to I/P) The diagram is on page 75, top left corner. Use that and you should be able to find the pinout the hard way using all the other pages. You just have to go through all the systems one at a time and look for the C100 connector in their individual wiring diagrams. It should tell you which grid location within the C100 connector. Its not as convienient as the one you linked to, thats for sure. Link to comment Share on other sites More sharing options...
35 Dollars Posted July 8, 2012 Author Share Posted July 8, 2012 Thanks DREDnot... page 75 of what? C100? Is that the connector that goes from the firewall to the fuse box, then to all of the interior gizmos? Ron Link to comment Share on other sites More sharing options...
DREDnot Posted July 8, 2012 Share Posted July 8, 2012 Page 75 of the 88 electrical troubleshooting manual. Thats what I assumed sloride scanned for you. If not, thats what you need. viewtopic.php?f=9&t=12734 I believe there are the same troubleshooting manuals for 87, and 86. I think Ive seen them on ebay. http://www.ebay.com/itm/1986-Jeep-Coman ... 03&vxp=mtr Link to comment Share on other sites More sharing options...
35 Dollars Posted July 8, 2012 Author Share Posted July 8, 2012 Thanks again, for the links. I ordered the book on ebay. That should help me get this straightened out. I truly appreciate the advice and the time you fellas took to help me out. Ron Link to comment Share on other sites More sharing options...
35 Dollars Posted July 13, 2012 Author Share Posted July 13, 2012 That book was awesome! Got it all figured out. Just to let you gentlemen know: the bulkhead connector of the XJ and the MJ are nearly identical give or take the rear window wiper/washer thingy. and one or two others. The only thing that I think is wrong is that I have to replace the instrument cluster of the V6 with the one from the EFI I6 Cherokee. If any of you fellas happen to have a spare I'm in the market for it. Ron Link to comment Share on other sites More sharing options...
