book me a flight and i'll help with the beer.

just have a go at it, read the ms site there is lots of info out there.
the relay box is easier then you think putting the wiring together.
fp = fuel pump, put wire there easy. at first looks like sheet. get some plugs, different coloured wires, draw it all down, once you have the plugs make the other end and connect to the realay board using the drawing you made to follow wires. thats your wiring harness done,
i have a ms file that will get you running and im sure andrew would donate his too.
would take you a few hours to make the wiring harness, assuming you buy all the right plugs and stuff unlike what i did.
plus if it breaks down you can fix it as you made it
