Intercooler Sprayer Wiring

The switch labeled Instercooler Spray Switch is a momentary pushbutton switch. The switch labeled JDM Spray Switch is an on/off pushbutton switch. Its purpose is to activate the Boost Pressure Switch, and operate in parallel with the momentary switch. Pins 2 and 4 are for illumination, and tap into the approiate wires from the Fog Light Switch...which occupies a space right next to the mounting location of the added switches. I guess that the only ground needed on the switches is for the illumination.

ya lol, he actually helped me going it going tonight. I have read every thread possible, but there was a slight difference with my setup as I was not going to use the factory timer. However, it appears the factory timer is setup exactly how a relay would be. I assume the timer IS a relay. So now, my plan is to get an alarm relay with an adjustable timer and use it as my relay.
