All the RWAL codes. Complete removal?

[obijuank5]

I’d like to un abs this 90 burb. It has shown tons of codes and is leaking on the dump valve anyways. I’m not fixing this.
At the moment the brakes do seem to function like they would without rwal.
How do I unwire it or can I just leave it unplugged? The tan, white, and black appear to head behind the distributor so I lost them there. Some head up under the dash behind the cluster. If possible I’d like to make this as if the truck never had it but I’m not sure if that’s realistic.
This is like a spaceship compared to the k30.

I’ll probably get these and a new proportioning valve. I’m pretty sure that’s it for the required parts to swap. Missing anything?
Thanks for the help.

Delete the garbage. Had to on my ‘91 as we couldn’t bleed the rears as the combination valve was stuck. They were not available through any part store then and that was 7+ years ago.

Get the lines and the combination valve that bolts to the front frame crossmember. You will only have to alter the tube nut for the rear line. You’ll see there is already a down on that front crossmember where the rear line starts. That tube nut will not fit the combo valve. There is just enough length to cut the end off, swap in the right size tube nut and reflare the line. Then it goes in like stock. Pitch the rwal garbage in the can.

When you get all the part numbers for this let me know, I’m pretty sure my rear brakes don’t work on my ‘91.
