On the back of the fuel pressure gauge on top is a rubber bung, you need to remove the bung and drill a small hole into it to equalize the air pressure inside the instrument. Doing this will stop the pressure drop as you climb higher. The internals are very sensitive to air pressure.

Wire as follows: One wire from "L" (lamp) on regulator to Pin 5 on Rpm/Hobbs meter and then from there to No charge light. Then one wire from "C" on the regulator to any +12v wire (RED) that is activated when you turn the master keyed switch to the ON position (Eg. any of the + (positive) terminals on the instruments. The ICP harness is wired like this and if you using the std panel layout, id use the harness as instructed. If you want to remove all the unnecessary wires in the harness, you can do that too.
