So this morning I installed an adjustable overflow valve and finally got my fuel pressure back in check.

after finishing I took my truck for a test drive. As soon as I got to the end of my road I noticed my ABS and brake lights were still on. I pulled the emergency brake handle again but they still stayed on.

The truck does run or stop any different then it did before. I did some searching in a bunch of forums and have read countless threads on this same problem. I first checked my wiring running from the RWSS Along the frame. It was chaffed through the protective loom but not through any of the wires. Then I ran up to advanced auto and picked up a new RWSS for 13 bucks. I installed it and pulled he neg battery cable and after driving 100yards the lights came right back on.

Any other ideas as to what it could be?

I haven't changed my rear differential fluid in a good bit so this weekend I'm going to that but I can't seem to find out what it could be.

Also I noticed : the old RWSS had a small metal piece on the bottom that I guess would read the exciter ring. The new one I got from advanced auto looked to be about the same but did no have that small metal piece on the bottom. Is this just a different style of sensor or is it not the right one?

Most likely what I've got right now. I've got a failed driver side sensor I can physically see the damaged lead. So I would consider replacing the sensors up front if the speedometer is still functional.
