can someone help me sort out my TPS sensor
 

i need to know what the wires do, its a 94

so i have four wires
red
blk/blu
grn/wht
red/blk

now i need to convert to a 3 wire tps on my edlebrock throttlebody
i belive its a gm tps

On your '94 harness, the grn/wht wire is the +5v reference, the blk/blu wie is ground, and the red/blk wire is the variable output.

Call Edelbrock and get the pinout for the TPS from them.
