    Can anyone tell me where I would find the module? I've got no abs light at all.

    Most likely located under center console(cup holders). 2004, I believe ABS light is in warning gauge strip above drivers windshield. Did you make sure bulb isn't burnt out?

    No I didn't check the light. I will, I wish it would be that simple. I'm almost certain the PO removed a lot of the components and wiring .

    Yea, the light might be corroded out. Simple check. And test for power at the pig tail for that light.

    Is the dash board light cycling off/on?

    Currently there is no light, no wiring from the sensors, and it looks the the air brake valve is a no abs type

    So some good news, the bulb was not pushed ask the way in. So I can confirm the ECM has power and the lights and relays are all working.

    The wiring to the pigtail is messed up somewhere, the centre pin has switched power from the dash for trailer backup light . But I'm very happy it seems like all the wiring in the cab is unmolested.
