Howdy from Texas!! I was given this vehicle free of charge only running in default mode! The distributor est pulse is not getting to the ECM sending it in to default mode after start up. looking for a pinout so the wiring can be checked. Any help or advice will be appreciated.

Thank You I will look that up. WAI remanufactured ECM support is sending pin outs for the ECM and Distributor so the wiring can be sorted!
