Hello!

I took my throttle body off to clean it, but forgot to mark the wires that go to the sensor on the left (as you're facing the car) side of it. There is a black/red and a brown/white one. Just need to know which is on top, and which is on the bottom. This is a '67 250SE.

Also, what is that sensor, exactly? It seems similar to Throttle Position Sensors on other cars I've owned. Does it mark when the throttle is wide open, or closed?

Thanks!
