Received the part back today...

Hooked it up and NO MORE LIGHT and the ABS works as it should. We got a few inches of snow this week and the shady part of my neighborhood was a great testing spot.

I would recommend the service discussed in this thread to anyone wanting to get their ABS groove back on...

Also as a note I did drive the VX with the electronic portion of the ABS removed and it was awful. Brakes locked up on tight turns ( think in/out of a parking space and riding the brake) and was very jerky...

This is really strange to me. Shouldn't the braking performance be the same with a non-functioning ABS controller and no controller? They way I think it works is you apply force to the brake pedal providing hydraulic pressure to all four brake calipers. When wheel slippage is detected the ABS controller rapidly opens and closes the solenoid associated with that wheel effectively pulsing the hydraulic pressure to that caliper. Having the ABS controller removed should provide normal non-abs braking. Right? Could there be another issue with the brakes that M H VX is experiencing?

OK so about one month later and two weekends in conditions where ABS is actually helpful (snow / slush / ice) up at Tahoe ABS module repaired by ASI went bad again. I am sure they will fix it for me free but it takes time / money to pull it out and esoecially reinstall since I need to bleed brakes. Is there a way to pull black part of it without touching break lines?

Yes, this is what I did.

Just loosen it from the bracket and loosen the brakelines mounted on the fender well and the firewall. Be careful or you will break the plastic retainers that hold the brake lines in place.

Gently move it up, so as not to crimp any brake lines and remove the six torx screws and the black module. You would have already removed the two electrical connections. Mount the silver box back into the bracket.

I drove mine with the black box removed and it drove terrible when braking and turning in tight places like parking spots or getting into my garage.

Just be careful and you'll be fine...

How do you disconnect the electrical plug under the harness connector? I was advised to press the pin that keeps the plug in place with a flat head screwdriver. However, can't seem to find by feel the release pin. I don't want to break the plug or anything else. I have not been able to see enough of the plug to figure out how to release a pin or whatever.

Anyone know of a link to an image of the plug?

Mile High VX, when you said "loosen" the brake lines what did you do?

TIA.
