A win tonight! I've been trying to nut through Holden schematics and get the seat controls working. Pretty easy to work out the main power supply circuits into the seats, but damned if i could get them to operate. Kept staring at the schematics and then spotted another sneaky +12VDC supply going into the seat memory controller and hooked it up as well. Bingo, seats go up...seats go down... That makes 3 x separately fused power supplies to the drivers seat to make it work...so far!
