Question Re: 1993 TrasSport 3.8L Quad Driver Codes 26 and 56

Thanks for the picture Blue Bowtie.
6 wires in that transmission harness; brown, white, green, black, yellow, red.
Red goes to three solenoids that I can see. Would that make red a 12V supply, and the other colors the designated grounds from the PCM?
I see yellow, black, and green going to 3 solenoids.
What do the brown and white control?
I will search for a schematic in the service manual.

If I jumper A and B terminals on the diagnostic socket with the key on will I be able to check all of the grounds at the round connector above the modulator? I think I saw that in the manual?

Is it absolutely necessary to undo a frame member and lower the transaxle to remove the side cover? I would want to remove the minimal amount of stuff to get at those solenoids. If I have to change one solenoid I would like to change them all while I'm in there?
