Re: ZEX Nitrous Install
99' Honda Civic EX. Also need to know which wire on the Throttle Position Sensor I need to tap into and what if I don't have an extra opening for the vacuum line off of the throttle body?
Thanks.

The throttle position sensor or (TPS) will be located on the throttle body on the opposite side ot the throttle linkage. The sensor is usually a three-wire sensor. The output wire will usually have between .5 and 1.2 volts at closed throttle and 3.5 to 4.75 volts at wide open throttle. Using a digital volt-ohm-meter (VOM), check the voltage on each wire of the TPS with the ignition in the ON position and the engine OFF. ONe wire will be ground (0volts). one wire will be near 5 volts, (DO NOT CONNECT TO THIS WIRE) the other wire is the output wire. Prove the wire while manually opening th throttle. The voltage should increase accorging to the opening throttle angle.
