you mention that there is a bad wire somewhere ? what is the bad wire that you know of?

There is a known issue with the 99-06 trucks that may be an issue on the older and/or newer trucks. anyways that issue is that the ABS pump/module grounding wire/strap under the truck on the frame rail nearest the module is known to be a bad connection.

I only mention this because i too have this issue however my issue is that BOTH the ABS and BRAKE light are intermittent together, both at the same time but never one at a time. after much research i have found the wire being an issue and cleaning and reconnecting the wire and grounding post seems to be the solution but i havent had time as of late to dig into it to see if it will fix my problem... YET.

I now have 4 of these 99-06 trucks and they ALL have the same ABS and BRAKE light issue. so i think that there is something to be said about the ground wire/strap on the frame. worth looking into anyways.

Thanks I'll check that out. The lights aren't intermittent. A while back id be driving the truck and come to a stop when all of the sudden the abs would kick in. I replaced a wheel bearing and the abs issue continued. My issue was the abs wire that connects to the hub assembly.
