Need help wiring up XE Throttle Body to Magna Head

[Colin034]

I am in the process of fuel injecting my Sigma, I have done most of the wiring but can't work out how to wire the XE throttle body, it has only 3 wires were the Magna throttle body has 4 wires
If anyone can help with this problem it would be appreciated.

OK if you look inside the Ford TPS the pins are identified top to bottom as ABC

A = Ground

B = Signal

C = +5v

Looking into the Mits TPS plug, (two small notches on the right one large on the left) the pins are identified top to bottom as 1234

1 = +5v

2 = Signal

3 = not used

4 = Ground
