91+ TPS on 90 harness

[91fwdtsi08]

I have 1990 eagle talon and a 91 6 bolt im putting in it. Im using 90 coil pack, power transistor, and cas. the throttle body is a 91+, but my question is how to splice in the 91+ TPS into the 90 harness. I have the connector for the 91+ TPS with 3 wires. The 90 harness has 4 wires on the plug. I have heard some things about the IPS plugging into the harness with the TPS wires. Can anyone help me with which wires go where. Thanks alot in advance

Well since know has said anything about this.What i would do is get a haynes book for 1990 and one for 1991,then i would check the difference in wiring.

According to my 90 FSM there are 4 wires on its A-55 connector.

Pin 1 Green IPS
Pin 2 Green/Black Sensor Ground
Pin 3 Green/Red +5v Sensor Power
Pin 4 Green/White TPS Output

The three wire colors on the 91+ TPS harness are the same and you need to run the green wire over to the IPS. On a 91+ car it's part of the harness going to the ISC rather than in with the TPS.
