One of the bad things about old jeeps are the fact they originally had cloth insulated wiring. The next bad thing are all of the bubba-fixes that are patched in there later. So now I have a jeep with a mix of both barely-insulated wiring and many wires for unknown functions that have accumulated over the years.
Fortunately about these old jeeps is that if you have a diagram and the proper tools you can rewire these babies in one day, front to back. Now that I have my new 12V charging and solid state ignition installed, I want to start cleaning up all the horrible wiring under my hood. Look at this mess:
My jeep has since had a keyed ignition installed, there’s some sort of light on the dash I have no idea what is for, and want to get it straightened out if not for aesthetics, then for knowledge of what did what under there. A fellow Cj2 owner provided me with a great diagram that he used with the same exact keyed ignition. (Thanks Captainpattson).
With this, it made a LOT more sense of what was supposed to be going on under there, what could be removed, what needed to be changed, re-routed and connected correctly. I bought wire that matched the colors of the diagram, got a generic box o’ wiring connectors at the parts store and tore into it….
MUCH better! Next I’m going to totally rewire the front headlights and light switch so I can think about getting this jeep road ready!
I know this may be a stupid request but I have been rewiring my 1948 jeep willys and I can everything working but the ignition and need some help. One difference I have is a voltage regulater and I continued to wire it as it was because not sure what else to do.
My real problem is trying to figure out what the box you have labeled AMP is. I have tried many different combinations and have not figured that out. It appears to control the ignition and light switch which I can not get either to work.
I think I have something wired backwards. On the back of the ignition it has BAT IGN ACC and in the center START. On the solenoid it has an ING & START so I ran the wire on the solenoid START to the START on the ignition and the solenoid IGN to the IGN on the ignition and BAT side of solenoid to the BAT of the ignition switch.
When I try the lights nothing or the ignition switch nothing. I can bypass the light switch and all the lights work and I can bypass the ignition and the starter works, just cannotn get it to work through the switches. Believe it may have something to do with the box AMP – what is it? Is it a switch, junction or what?
Thanks for any help you can give me…OH yes I have a 12 volt system.

The amp is the amp gauge on the dash.
Thanx. It helped me greatly. 🙂 🙂
