I’m sure I can find the throttle position sensor, but which wire should I tap into for the ZEX activation at W.O.T.

 

 

There are three wires going to the civic throttle position sensor:
Breen/black
Yellow/blue
Red/black

One of the wires form ZEX box is supposed to be connected to the WOT switch:
White

Which wire (green, yellow, or red) is the white (ZEX) wired supposed to be connected to?

 

Is it the RED/black wire?

Honda civic (1996-1998) and Accura Integra (1994-1998) Haynes “Automotive Repair Manual”
“…connect the probes of the voltmeter to the red/black wire and ground.”
“Gradually open the throttle valve and observe the TPS voltage. With the throttle valve fully closed, the voltage should read approximately 0.5 volts. Slowly move the throttle valve and see if the voltage changes as the sensor travels from idle to full throttle. The voltage should increase smoothly to approximately 4.5 volts.”

Can any one confirm this.

 

Yes thats correct (the voltages).

 

I know the voltage is correct because I got it out of the manual, but is this the wire I hook it up to?

RED/BLACK --> WHITE

 

Find the wire that has 4.5 volts on it when at WOT, and connect it to that.
