Is there also a key to what the lables are. Some are easy like RD=Red. But what do the numbers mean like 9 in the pic.

Does anyone recommend a vendor to purchase automotive wires for "Jeep" or a highly used brand? I stripped a wire while installing a mod and need to repair. Looking at 0.35 and 0.50 wire. Thanks for posting these resources too! Dealership quoted me 2512k for a diagnostic and soldering fix... price point going to labor and them spending an estimated 11 hours on the JL...

A local friend of mine who works at another shop quoted me a burger over a weekend to help fix the wire and test fuses.

Just go down to your local wreaking yard and get a chunk of harness off a newer vehicle.

Are these diagrams for the 2018 JL or 2019? I see that TechAuthority sells the diagrams for the 2018 Wrangler but not 2019 so it got me wondering

Wiring Diagram Question for a Knowledgeable One:

Does the reference 1.5 and 2.0 for example refer to wire size? That would be useful in determining what size wire tap to use for relays, etc.

Thanks!

it is Circuit Breaker CB01 25 Amp
I see this large gauge wire (pink and yellow) terminates under the passenger seat. It must be the power supply for the rear window lift motors. (I have a 2 door) it is ignition switched and fused 25 amp. Can I run two seat heater circuits (additionally fused at 7.5 amps each) from this 12v source?

I hooked it up temporarily with both heaters on high and tried both windows. The breaker didnt trip.

I’m assuming the 25 amp breaker is enough for windows, not just 2.

I would Identify the heated seat circuit and use that by inserting a fuse in the Fuse box.

You can figure the current draw Voltage divided by Resistance

I’m assuming the 25 amp breaker is enough for windows, not just 2.
Need to do the math to make sure.

Can someone tell me which fuse / wire run is the ACC for the radio. My radio only turns on when ignition in run mode and does not turn on ACC (accessory) ignition.
And i can't figure out what wire or fuse is the ACC on the radio wire harness.
Thanks
