Re: What wires to get rid of

LEVE

how closely does your diagram represent an 85 CJ7?

i am rewiring also and would like to get rid of a lot of "junk".

i took off the wires and didn't label them properly and now i can't firgure out where much goes. plus i can't figure out my chiltons and haynes electricity diagrams

what's the MCU look like? or isn't there one on a CJ?
what's the ingnition module look like?

because i'm asking the last two questions does that mean i should have someone else put it back together for me?

thank
patrick

Re: What wires to get rid of

1. The wiring colors can vary from shade and year.
2. The important thing is,
3. They're the same from from distributor to ignition module.
4. All you really have to do,
5. Is simply connect the Distributor wires,
6. To the Ignition module wires.
7. Purple to Purple,
8. Pink to Pink, etc.
9. It's that simple.
10. For $10 an hour...
11. And a plane ticket...
12. I'll make house calls! [img]images/graemlins/grin.gif[/img]

Re: What wires to get rid of

Your MCU (IE:computer or brain) is under the dash tucked up behind the glove box. You can kind of get to it from under the dash but you're better off just pulling your glove box. It's a little rectangular box about 6"x8" with a big mess of wires coming out. You do have one in an 85 CJ, it controls the stepper motor on the stock carb and the ignition timing advance I think.

The ignition Module is a small squarish box under the hood mounted on the wheelwell.

Re: What wires to get rid of

No "easy" way. Pull the ECU and follow all of the wires that are in the loom and remove them. LEVE's diagram is great. It took me a Saturday morning to do it and run a new wire loom. I believe that I had to make one splice in the ignition line. Ended up removing a boxload of wires and looms. Much cleaner, less "mystery", and I swear I saw the front end raise up [img]images/graemlins/grin.gif[/img].

Re: What wires to get rid of

Thanks for the replies. Sorry I haven't responded for a while, haven't had access to the net. I went ahead and cut all the wires at the computer(well, I left about a foot of wire)and took it out. There are still more wires than I want in there but I'll assume that those have to stay, not including wires for the winch, lights, etc. My 3/4 wire loom is packed with wires(almost have to go 1"). Oh well, can't be too picky. appreciate the help.
