I have code P1633 - as far as I've check all the fuses in the power distribution (engine fuse) box have continuity - I don't know how to test relays?

Next up I want to check where the harness plugs into PCM if there is power there but I don't know which wires/pins to check for voltage and I can't find a diagram that labels the pins on the connectors.

Any help would be appreciated.
