What gauges of wire do you use mostly for your harness?
Battery terminal to ground and to starter: 00AWG
Main feed from battery terminal via a 40A relay to fuse box and alternator to battery terminal: 9.5AWG
Main feed from 15A fuse to light switch/ignition key: 11AWG
Starter switch wires: 13AWG(once ignition key is on, the main feed relay is actuated which feeds the relays for lights etc)
Tail/trailer socket wires: 15AWG
Control wires from light switch to relays: 15AWG
Since I have an electrical temp gauge I have wired it also with 15AWG as well as turn signals and oil/gen indicators, I replaced the old style ground terminals(ring terminal) with spade connectors for easy disconnection and reassembly.
I have a total of three used fuses out of four possible, one is a 20 or 25A fuse for the main relay, one 15A for thermostart and starter, and one 10A for the rest(might have to change this one to 15A if I plug a trailer to it)
How do you colour code the wires?
Ground(in my case negative ground): Black
Feed from battery to switches, "live side": Red
Switch - Lo beam: Yellow
Switch - Hi beam: Yellow w. green tracer(normal ground wire colour)
Switch - Instrument lights, tail lights and trailer socket tail: Grey and Brown(I've parallel wired grey and brown in my trailer socket)
Temp gauge - Temp meter: black as this serves as "ground"
Oil pressure gauge - Indicator light: brown
Alternator B+ - battery: red
Alternator D+(charging light) - indicator light: yellow
Starter switch - Starter: red(this one's easily distinguished in my loom since it's the only red wire going from the dash and forward)
Switch - Thermostart: 13AWG brown(this one's a slightly different shade of brown than the one for trailer socket)
Switch - signal horn: blue 13AWG(darker blue than right hand turn signal)
Right hand turn signal: blue
Left hand turn signal: green
What is the hose you use?
It looks just like this one:
http://www.texit.se/produkter/skyddslang/slitflex/ But it's not slit along it's length and cannot be used with an existing loom but only when making a loom from scratch, it's flexible and pretty durable which makes it quite appropriate for use on a tractor or other agricultural equipment...
These images show a little of it...
Upper dash loom(s):

Front part wiring loom as it's passing by the starter:

These "hoses" are available in several different diameters and one should take note that it is the black UV-tolerant variety that's used(it's a lot more flexible than the cheaper non UV-tolerant that's used for wiring inside house walls)
I'd advise anyone that's bent on making their own loom to write a short list of which functions are needed/wanted and their cable colors and also the wire gauge and I encourage you if possible to use wire coloring that either is identical to the vehicles original loom or if you make up your own colors, don't use the same wire gauge and color on two wires running the same way in the loom as this will probably give you headache the day you need to fix something
I did it because I didn't have that many colors to pick from and I didn't run the same color and gauge wire twice in the same loom...
Thanks,
You're very welcome
