Jeep Wrangler PCM and module repair and replacement

What did you do to your TJ today?

Check out the Rocket City wrangler Facebook page post there is a camera image of a very identifiable rig that may belong to American four-wheel-drive outfitters that allegedly hit a roadside worker and kept going Saturday in route to a ride at Coalmont the same company had organized.

IF it's the one I saw on another page, the owner has been in contact with local police. The incident I was referring to involved a guy hitting a road worker holding a rake, and the wrangler was recently sold to some older guy before the incident.

NON TJ Update. @Chris feel free to remove this.
After fixing my fuel pump wiring thanks to @macleanflood's help with finding the broken wiring issues today, I got a call this afternoon that the masses I had removed on the 12th weren't colon cancer. I have other issues but nothing that can't be fixed. Thank GOD EVERYDAY!!!

Son drove my TJ home from Illinois on Saturday. Started experiencing a soft brake pedal. Check fluid, but it remained full.

Noticed a baseball sized black stain on the driveway Sunday morning. I pulled the Jeep into the carport and pulled the passenger rear tire off. The wheel cylinder I replaced right before taking it up to him in July was not the problem. The fluid was gear oil. Saturated shoes do not provide friction for stopping. I noticed the driver's side was just beginning to show leakage as well.

Dropped it off at my buddy's shop to figure out why new axle seals are leaking.

Always something.

caught in a bicycle chain. I suspect mice

Your mice ride bicycles? I guess that's better than a motorcycle gang.

Glad you got it sorted. I think I've counted at least a half dozen unnecessary fuel pump swaps on the forums because they didn't check wiring first.

Swapped out the broken spring and shock as soon as they arrived today but I think these extended sway-bar links are a little bit too long.

I need @John Cooper's help with this wiring issue.
My Rubicon lockers finally failed. I don't blame the factory design after working perfectly for 23 years. I blame my HOA for making me park it a few miles away in the woods. Can you diagnose why they failed? The mice claim it's a factory defect. :unsure:
ps. Can I rewire it to switches directly from the two plugs near the pumps or is it more complicated than that? Total of 5 wires chewed through.

HOA’s are precisely why you guys should never have left the empire.

Yes you can, I just followed Jerry Bransford write up, it's here in the site.

I relocated my pumps to the ABS tray under the hood.
