hook them both together and then to 12v ignition. the pump wire closer to the flywheel is for the fuel feed. the pump wire closer to the crank is suppose to be for better fuel economy less power.

He is referring to the stop solenoid and timing advance wires, which i dont think is what you meant.
Are the two wires you mentioned going into something that threads into the pump head like a sensor?
I have never seen a vw diesel pump that had wires there, its usually just a plug bolt.
That hole is used to thread in a dial indicator to time the injection based on plunger position inside the pump.

in the pic on the injection pump there are 2 wires, one with a hard white plastic covering the injection pump, and another with black. the white one is the fuel cut off switch the black one is the economy one.
sorry about the pic the best i have that is already online

any chance of getting a picture of the pump? are you sure its a 1.9TD pump? the only pumps ive seen with wires there were on 6.5L chevy TDs which are electronically controlled.
