1/ with the ignition on and the kill switch in the run position, i'm only getting 1.25V ish out of the fuel pump connector, i'd have thought it should be 12 ish, especialy as the manual states to test the fuel pump you connect it directly to the battery give the "in" side a drink and it should squirt from the "out" side of the pump,
2/ i've got a connector under the pilot seat with 1 red wire 1 brown wire that isn't connected to anything, i found this pic
