I tried another gas tank, and turns out the fuel pump on the red one was probably bad, cuz the blue one actually primes. And leaks gas everywhere. So far I've got fuel pump prime, servos that sound like they may be the choke? and that's pretty much it. No cranky.
So the squareish plug actually plugs into the airbox, but I found another squarish plug without a mate right on top of the fuel rail looks like, with no mate. So that leaves me with one square-metal clip type and one oval behind teh throttle bodies, and one oval type in front of the throttle bodies.
