I had a few questions... I just finished putting an LS-VTEC into a 97 LS. For the VTEC wiring I know I have to run the VTEC solenoid (pin 8) and the VTEC Pressure switch (pin 15). Ive seen that the connector for the pressure switch has 2 wires, is one of them a ground? Also, do I have to wire up the IACV?? If so, where is the IACV located??
