Ok according to my 2001 FSM (pg 5-119), all of the wires for each WSS go to the EBCM (electronic brake control module). There are 2 wires per sensor, a low reference and a signal. I guess it doesn't matter if you interupt the reference or the signal. Just find the 4 proper wires (as Rogue has stated that he now runs with all 4 of his disconnected), jumper them with some low loss relays and then run 1 wire into the dash for your switch.

Here'* the connector view to the EBCM (atleast for the '00+):

isnt there an ABS fuse you could wire into to break the ground and kill the ABS completely? Im pretty sure there is on my Regal, just not so sure about a Bonne.

This is interesting and I'm following it pretty closely to see whats happening but to be honest I would not want to introduce another point of failure to the ABS/TC system. It takes litereally 30 seconds to remove the WSS'* and I just leave them off for most good weather driving. If it rains or snows I hook em back up.

PDad.... how are things going?

One could rig up a relaty inline with the ABS setup, instead of all the wiring. When it'* switched on, you have ABS due to a open Relay, when it'* off, you shut off the flow.

Your switch can trigger multiple relays to multiple systems.

I worried about that too......

Rogue, when you disconnect the WSS (this of course kills your TC)... is there anyway to tell from the "cockpit" that your WSS are pulled....?

Yes, the ABS and BRAKE lights come on and the DIC says Service Stability System (at least on 2k+)

Guys (Rogue/PDad) what do you think?
Will disabling the brake and tc, thus disabling magnasteer be critical?
Or does disabling the WSS kill the magnasteer anyways?

For some reason, I believe it works with the VSS.

Interesting question. I have noticed the steering feels a bit sloppy to me with the WSS disconnected but I thought it was just me, or more power being let loose to the wheels makeing it feel different. I never thought about magnasteer being affected.
