the first thing i am unsure about is what needs to be completely cut from the OEM harness and what needs to just be spliced into.
here is my guesses, please correct me if i am wrong
TPS-rewire to autronic
Air intake Temp-(self explanatory, came with Autronic)
Coolant Temp Sensor-leave in OEM sensor, rewire to Autronic(does this need to just be spliced?)
TPS Rewire, for an Automatic Car, you'll need to tap instead of redirect the wire. Be careful to wire in the wiper and ground only, no need for the voltage feed to the Autronic. This will help in the kickdown of your tranny. (This is a guess, but there's no other choice)
You'll need to splice the OEM Water temp sensor if you are using the OEM one. I'm using 2, 1 for the factory temp guage, and 1 (supplied by Autronic) for the Autronic ECU that's mounted on a tap pipe in line in the top rad hose.
Use the OEM Rear O2 sensor, not the 6 wire one. Under the Autronic Menu under M1, select AF Sensor and Select, Direct 92 connection for the A/F sensor, and under the A/F-02 span, select SMC (it's already pre-configured in the CAL file I sent you.
Don't touch the IAC...
Fuel Pump Wiring, don't touch. Just replace the pump...
