As you know, I put the car on it's wheels at the weekend. The fuel lines are complete, and that leaves me with one more job before I can tell if my engine rebuild was successful - wiring her up.
I've not got the original Beemer loom, and neither have I bought the loom from Marlin. What I do have is this:

Which I bought at Stoneleigh this year.
Broadly speaking, it should be easy with this - but I'm a little aprehensive about the whole process.
I'm a little unclear on somethings... Such as:
I have two fuel pumps - I assume that each will need it's own relay. There is a fuel relay on the engine harness, and one on the wiring module. Can I the engine one for the HP pump, and the module one for the LP pump?
Cable - I need to several different sizes to accomodate the current draw of different parts of the car, but how much do you think will be required? I don't want to buy 10's of meters of cable when 50cm will do.
I've also been thinking that I could do the whole car in a couple of colours of cable, therefore saving money as I can buy in bigger quantities of each size - but then identify each circuit with these:

Or is that bad form? The majority of it will be wrapped up in loom tape anyway...
Also, what's the minimum wiring required to fire her up?
Pumps,
Ignition circuits,
Oil pressure warning light
ECU
Anything else?
