Hi,

Could anyone help me out with figuring how the brake pedal switch is connected to the ABS, there seems to be more going on than just the switch.

Thanks,

Here's the diagram from a 1998, maybe it will help.

It looks like the feed to the stoplamp switch is hot, and when the brake is released it is an input to the brake control module (Kelsey Hayes unit).

Thanks a bunch east302, that does help. What i am seing is that the input to the brake controller remains hot even when the pedal is pressed. ABS still seems to work though!

Its a really useful diagram, what publication did they come from? was it the 2 volume OEM Service manual?

It's from alldatadiy.com. An annual subscription is around $30, it looks to be the same as (or closely mimic) the factory manual.

I love the wiring diagrams on alldatadiy, they're extremely useful. Some of the rest of their content is garbage and rather useless IMO.
