Power seat wiring question

[davy crockett]

I have some 05 Sport Trac power buckets I'm adding to my 93 Ex.

One thing I haven't figured out yet, there is a yellow/blue wire on the main harness into the seats that I believe supplies power from one seat to the other.

Can anyone confirm this is in fact the purpose of this wire?

There should be a Dark Green wire that supplies power to each power seat switch individually. The Yellow/Light blue wire is for rearward movement on each seat.

Ok, thanks, that makes more sense. I just couldn't find the source for that wire in the shop manual.

So does that supply power only for the one function? The other two motors and heater/lumbar are all supplied by the green wire?

I know the green wire is a 20A feed, would 20A be enough for the yellow/blue as well?
