I have 95 1500 that i finally got running, only a couple of small issues left to rectifiy. The abs and parking brake lights come on after the key is the on position for approx. 20s( as soon as my headlights go off the abs and parking lights come on) Changed the rear diff speed sensor, no change. I put the sensor in last night and check the system electrically but didn't drive it. This morning I started off to work and the brakes did not feel right so I left it home today. The front brakes were making grinding like noises when I pushed the pedal, they were engaging because my truck was stooping.

What else can I check for the abs and parking light problem. Does anyone know where I can get a wiring diagram for this circuit for my truck?

As for the grinding like noise- 1- it didn't do this before last night, I was checking the proporting valve and I could feel the spool move out at the end of the valve as soon as my brake pedal felt pressure. I'm not sure if i re-connected the single connector to the proporting valve , if dis- connected, what would happen.
Thanks in advance

 

Haynes manual is your best bet for 95, as far as I can tell, it has both ckt's listed. The 2001 fsm download is probably quite different, but you can look.

 

Where's is the RWAL control module located or is that a part of the PCM?

 

OK I found the module and the test connection, start raining will try to pull codes of it tomorrow

Thanks
