I have a 1994 Grand Prix. Does any one know where I can get or happen to have the wiring diagram/schematics for the anti-lock brake system? Even just the plug pinout for the control module under the driver side dash. No one around here has the right equipment to retrieve the trouble codes or does not want to be bothered because it is not OBDII. The local Pontiac dealer wants $95 minimum labor charge just to plug their bidirectional scan tool in and record the codes for me I have over 11 years experience with 12 volt electronics and trouble shooting... a schematic would be a HUGE help. Any leads would be greatly appreciated. Thanks!
