I added this to my site. It's a short one, so I can post everything here. If you want to see the entire page, it can be seen here

Hook up the power probe to a 12v power source such as your car body. Attach a alligator clamp jumper to the ground on the Power Probe (yellow) and another jumper to the needle of the power probe (red). Give the inside of the ICV a good cleaning. I sprayed carburetor cleaner first for cleaning, then WD-40 for lubrication.

There are three terminals on the ICV. The center terminal is positive, so attach the positive lead to this terminal. The two outside terminals are ground. The ICV works by swapping ground rather than swapping positive electricity.

Attach the positive jumper to the middle terminal, and the ground jumper to the top terminal. Give 12 volts to the ICV either by pushing the button on a Power Probe, or whatever archaic method you wish to use.

This should close the ICV.

Swap the ground jumper to the bottom terminal. Once again, give the ICV 12 volts.

This should open the ICV.

The action should be quick and snappy
