Default 1994 ABS pump

I have been trouble shooting my ABS lights(service ASR and service ABS) for some time now. I have searched and referred to probably most if not all the threads on this issue and one, which I can no longer find had a picture and the instructions on how to apply 12v jumper wire to the pump to check its operating properly.
I'm down to the relays which I think are good and would appreciate if someone can find that thread or tell me how to jump start the pump and what two pins leads to use. Thanks

Mine turned out to be a bad EBCM(electronic brake control module). The box bolted to the inside next to the pump. After replacing that which I found on eBay and very important, clearing the fault codes, it all works as advertised now.
