What did you do with your DII today?
That sucks, but LR is not the OEM trailer wiring harness location, it's located on the RR. Gotta love aftermarket trailer wiring! Whenever I buy any vehicle and it's got an aftermarket trailer wiring adapter no matter what it is = I remove it ASAP. I only have one 04 Model and it's tail lights are in great shape (still drilled holes in them). The 99-02 tail lights are made way better IMHO. Glad you caught that before it took off on ya.
Get yourself a meter, a 2 wire trailer tail light/boat plug, and remove your shuttle valve switches, meter them, install the 2 wire lead (if your switches meter out as good) onto the shuttle valve switches, then run the wires out the bottom of the shuttle valve switch assembly, then cut the Yellow/Green back about 5-6 inches from the WABCO Unit, connect one end of the 2 wire harness to the Yellow/Green wire (heading back to the SLABS Unit aka Vehicle Side), then take the other side of your 2 wire harness and ground it on the AC Line bolt right by the WABCO Unit. You've now successfully bypassed the internal weak link inside the WABCO Unit with the Option B Mod.
After that troubleshooting will be wheel sensors for the most part. Also a scantool that can read LR ABS fault codes is highly recommended if you want to diagnose them quickly. Also you can't just reset the ABS faults with a normal OBD2 Reader, it has to be able to read the LR Specific faults in order to clear them properly. So many people do work on their ABS faults by replacing parts or performing Option B, but never clear the faults.

Sand blasted the chassis
Cut out some rust and welded in some 3/16\" steel plates. Once I'm done with the rust repairs I'll POR-15 everything I can. Bedliner coat everything else.
Also sandblasted the OE brushgaurd and coated with bedliner.
I extended the length of my rear ABS cables after I installed longer SS Braided Brake Lines. I bought a pair of front ABS Sensors, then I even went a step further as both my OEM connectors were just crumbling to bits. I bought 2 of the 2 wire harness connectors I normally use for Option B installs. I then cut the end off the ABS sensor wire, spliced in the 2 wire harness, then I covered everything with heatshrink so it looks as OEM as possible and it's protected. Then I added the other side to the OEM harness that leads back to the SLABS Unit. Now I have a much more durable connector, longer ABS Cables, and I have the connector up safe n sound above the frame.
I also adjusted the slack in my CC/TB Cables. Gonna slap on some from Aux Lights tomorrow & then I'm off to Austin, TX to see some friends, and then I'll head over to Marble Fall's and be onsite bright and early for the Hill Country Rover Rally at Hidden Falls Adventure Park Friday morning. It's been raining on/off there so I've been told the waterfalls are flowing, and there are several water crossings now.

Sweet see ya there! I'm gonna head up tomorrow evening/afternoon, visit my LR Buddies at Austin Roverworks, then I'll head to Marble Falls Thursday night where I'm staying then I'll be onsite first thing Friday morning. Wish it was a bit drier out, but no dust on the trails that's for sure!
