Only down side I've seen is if you need to bleed the rear brakes for whatever reason you need a power bleeder on the master cylinder to force fluid past the ABS or maybe plug the wires back in.

Dynamic Rear Proportioning (DRP)
The dynamic rear proportioning (DRP) is a control system that replaces the hydraulic proportioning function of the mechanical proportioning valve in the base brake system.
The DRP control system is part of the operation software in the EBCM. The DRP uses active control with existing ABS in order to regulate the vehicle's rear brake pressure.
The red brake warning indicator is illuminated when the dynamic rear proportioning function is disabled.

Corsemoto wrote:On 2000 or so and up, disconnecting/disabling ABS will also disable Dynamic Rear Proportioning (DRP) which will mean the rear locks up much earlier than the front and significantly decreases overall brake performance. I experienced this with ABS disabled on my van before fixing EBCM. Maybe it more noticeable with rear disc brakes, but it was problematic on any kind of slippery road surface.Dynamic Rear Proportioning (DRP)

Is this in the van you're selling? I think it would be more prudent to leave as-is so potential buyer has an idea what they are getting into as opposed to maybe not knowing because you have disable warning lights?

My light came on in 2001 when I cut the wires. oops.

That thing took forever to burn out, it outlived the black tape twice!

My '03 has ALL of them unhooked and now the ABS can't screw up and NOT let fluid get to any wheels as does happen from time to time when the sensors go wacko. It happened on the Green '98 that Mike H has now and on this '03. It also happened on my '06 Colorado, that one was an easy fix though so that's what I did there. BUT !! driving with an ABS that isn't working correctly is asking for it. I drove the '03 all winter with the ABS out of the system with no problems but I didn't start driving yesterday.

Unplugging the EBCM is not a fix or solution and should only be used as a temporary measure until the EBCM can be repaired. With EBCM disconnected, the rear brake proportioning does not function properly (or at all) and will cause rear brake lock up under heavy braking or on slippery road surfaces. I feel like it's a disservice to tell people to just disconnect and say it's better without mentioning any of the potentially negative and serious consequences.

So, you're saying that a possible locking of the rear wheels that has never happened to me is worse than having the brake pedal feel like a brick is under it and you have no brakes at all ? BTW, if this does happen to you, don't try to overpower the system. You just can't push hard enough. IF you have time, pump the brake pedal and on one of the pumps they will start working again. If you don't have time, kiss the front end of your ride good by.
