I'm just wrapping up a several month long project to refresh the top end and do the WP/TB on my 86.5. It's turning out pretty nice, but I'm not sure how to reconnect the TPS. I didn't label the wires and one of the plugs had crumbled apart. I should probably replace the short wire with it's two plugs, but I'm eager to crank it up, so will probably connect it as is for a while.

Obviously the middle one goes in the middle hole, but not sure about the other two. Anyone know how to tell where each of the end wires goes?

I know the top pin is the idle, if you put a dmm on the center to it it should show a short (switch closed) until you open the throttle.
So using this and the shape of the mounting bracket you should be able to get it right, the lower is WOT

Hope this helps

Thanks Dave, I also just found in the WSM where it describes testing TPS functionality at the LH computer plug, so I should be able to plug in all three and be able to see if it's right testing for continuity at the specified pins of the LH plug.

Can you see the wire colors? Brown is common (pin 1), White/Red is the WOT switch (pin 3) (closed @ WOT), White is the idle switch (pin 2) (Closed @ Idle).
