I'm in the process of removing TCS from a '93 Aero and have some questions about wiring.
Background:
Reprogrammed the Trionic 5.2 ECU to remove TCS
Removed the TCS throttle body
Added a throttle body from 91 9kt
Added AIC and hoses from 91 9kt
Modified throttle cable
I now need to connect the TPS and AIC. I've sourced new connector shells, pins, and seals to make some new harnesses for these two components.
I've been looking over the wiring diagrams to verify exactly how to connect the two "new" components and ran into a few snags.
First, TPS:
In the 1993 wiring diagram, the TPS (called "Throttle Angle Sensor") shows three connections, but they are only identified by color, not pin numbers. I found an older wiring diagram (1992, I think) with call-outs for pin numbers, so I /believe/ this is the proper method to connect TPS.
Pin 1 (Green-Red) connects to Pin 42 of the ECU
Pin 2 (Black-White) connects to Ground
Pin 3 (Gray) connects to Pin 45 of the ECU
Can anybody confirm this?
Next, AIC:
In the 1993 wiring diagram, the AIC ("Engine Idle Speed Control") shows only two pins, which connect as follows:
Pin 1 (Blue-White) connects to Ground
Pin 2 (Blue-Red) connects to Pin 49 of the ECU
However, the AIC I'm using (again, from a 91 9kt) has *three* pins.
Pin 1 (Blue-White)
Pin 2 (Blue-Red)
Pin 3 (Green-Gray)
Pins 1&2 of the 3-wire AIC seems to match Pins 1&2 of the 2-wire AIC, so I can connect those according to the 93 wiring diagram, but then I'm not sure where to connect Pin 3. Any thoughts? Should I try to find one of the 2-wire AIC's?
I had the car out and drove around the block last weekend. I'm getting close! Thanks for any help with these last few items!
