Looking for a wiring diagram for abs wiring on 87 sierra. I am having problems getting the servo pump running as there is no power going to it.
There was a problem with the pump and i changed it and can power it up when i bring a direct power to it. I seem to be missing a ignition live
to the abs relay so i would appreciate a wiring diagram if somebody has one. All i really want is the pump working so i have servo assistance .
Is there a way it can be wired up without having the ABS working.

 

Have you checked your relay is triggering ok

 

Relay is not triggering and the relay is ok. It's missing the live to the relay that triggers it. Also have no live at the ecu so I'm assuming I have a wiring issue some place so could do with a wiring diagram.
