I currently have an ABS light that is on, I went to have the code read and found out there is no power at the plug. Is there a way to find out the schematic for the wiring on the plug? I tried to follow the wires but it is imposable to trace it to the source. I would like to re wire a 12 volt lead to the proper pin.
Being a conversion it appears the wires might have been cut during the make over. The chassis is a P30 Chevy with a 454 ci motor. Thanks for the help.

If I have got the right vehicle diagram. 1997 P30 cutaway commercial chassis then ther is 4 wires?
Going to the DLC on the left interior bulkhead near relay bracket?

Wires
1) purple - is serial data wire from VCM (vehicle control module)

4) black - to earth/ground at left interior bulkhead near relay plate

5) black - to earth/ground on rear of cylinder block

16) orange - to engine/battery fuse at I/P fuse box 15 amp
