How do you test with a meter? I I checked resistance at the connector but it only shows open circuit even if I push one or both of the switches? The option B write up only has specs for resistance thought the entire thing. I am guessing open circuit is bad.
Thanks every one for their help.

Zach- You are going to want to do this as well with your 3 amigos repair:

Do the job once and do it right. If memory serves, the Amigos repair also talks about this.

Not sure I'd call it super complex, difficult to work on without the proper diagnostic tools sure, but hardware wise it's nothing vs stuff from 2010 & up on almost all newer vehicles. Just an ABS Modulator (Wabco Unit), ECU (SLABS Unit), Master Cylinder, Brake Switch, and 4 wheel sensors.
Like I said before Option B is preventative maintenance as that connection in the WABCO Unit will eventually fail, so that modification eliminates that issue for good, which then simplifies diagnosis.
I have yet to do the Option B mod/upgrade and say to myself well that was a waste of time.

You must have a scantool which is capable of pulling LR specific faults from the SLABS Unit. You can wait until you get a scantool to read the actual fault codes, but I'm willing to go out on a limb here and say your Shuttle Valve Switch wiring is probably cracked to pieces or not even there period. Then the internal connection inside the Wabco Unit itself is probably messed up so IMHO I'd perform Option B while trying to locate a good scantool like the iCarsoft LRII or the model just below it to verify the codes. D2's aren't getting any younger and years and years of neglect 3 Amigo wise means it honestly just needs Option B performed (you can re-insulate the original Shuttle Valve Switches normally vs buying a new one) then clear the faults and if it comes back it'll probably just be a bad ABS sensor connection or ABS Sensor/Hub Assembly. After that enjoy HDC/ABS/TC function!
