I have posted a few pics already but I thought I would do a diy thread.
I had to juggle this instal around work so it took alot longer than I hoped but anyway.
most of the work was done a couple of weeks ago on my last leave. today I installed the wiring. it came pre wired but I wanted it in a j-box and the loom wouldnt fit in so I rewired it and tested it today and it works..happy days. It has an 80L/min davis craig pump . which is 2 speed. A 1.6 ohm resistor gives the pump 5.5v for the slow speed and it has a pressure switch which switches at 7 psi, switching a relay to bypass the resistor and give the pump a full 12 volts. I also has a timer which is delay off. When I drop below 7 psi it keeps the pump at full speed for 20 second to help remove any excess heat. here is a few pics
