Another Question

Still going on with this BU0836A deal. The main reason I wanted to get one of these is to re-wire a Suncom SFS Throttle (HERE), and people said they could do it with this and it worked great. But, the throttle doesn't use pots, it has some sort of variable resistance type thing with only two wires whereas the BU0836A has three inputs (ground, input, and +5V) and I don't know what to connect to what to make it work. I have hooked the throttle up to a multimeter, and it does have a variable resistance. Does anyone know how to make this work? Thanks again for all the help.
