Wiring up a motor is often said to be the most difficult part of an engine conversion. I guess it all depends what you know, what your friends know, and what tools you have. I don't have a welder, so getting stuff welded up is always the biggest hurdle for me. Big thanks to Glenn & Brendan from Nite Parts here for helping us all out heaps. :) Anyways, back to wiring, all you need here is a little bit of patience, and the following:
1.) Wiring diaghram, Nite Parts supplied mine.
2.) Soldering iron, solder. 25W is fine. 40W is nice. Anything bigger is getting crazy. :P
3.) Electrical tape.
4.) Side cutters.
5.) Relay (IMHO), connectors, like eyes and bullet, etc.
6.) Multimeter. Use need 0-20V and also Resitance, 0-10,000 Ohm.
Just remember this one thing... There will always be something that you are not prepared for. ... normally 2,3, a dozen things... but this will always push out the 'estimated' time taken to 2 or 3 times what was thought.

Wiring

• First step is to just plug everything in, just lay it over the engine. Don't deloom it yet.


• Plug in everything you can.


• Power:
  Now, you need to power 4 wires, Ignition Power, TVIS power, and Injector Power, Cold Start Power. For these, I suggest running a relay that is switched by the "on" position on your key barrell. Or, you can just tap this wire for the powers, it is known to work okay, but I personally prefer the relay method then potentially overdraw the ignition circuit. Wire colour is normally black with yellow stripe for ignition.


• (Cold) Start wire, run a wire from the start wires on the ignition barrell.


• Constant power, for the ecu's memory. Just run a wire straight from battery for this, or use the Constant power on your key barrel.


• Alternator:
  Factory alternator tends to be externally regulated, with a black box in the engine bay, real messy setup. The 4AGE internal circuit alternator takes 4 wires.
  1 big mutha that goes straight to the battery, this one is normally black I think and is the one bolted on with a eye terminal and a 10mm nut. Constant 12 or 14Volts
  In the plug you've got:
  Large white wire, (B?) which goes straight to battery, the charge wire I think. Constant 12 or 14Volts
  Ignition wire... (S).just when key is 'on' it goes. 12 or 14Volts Ignition only.
  Light wire, (L), for the light on your dash, it's a small black wire, only a few volts running through it, if you put 12V down it you can kill the alternator, so best to be careful/test this one.
  You can get all these sources from the existing wiring... just need to tap into it before it would normally go to alternator. :)


• Engine earth by the passenger engine mount is done up.


• Head earth on the passenger side above the #4 exhaust port is done up.


• Injector earth is bolted to something, normally between 2-3 intake runners.


• Coil leads all in right order, 1-3-4-2. Coil -> Dizzy HT lead attached.


• Fuel pump. Here I would run a relay switched by the ignition, and not worry about the standard 4AGE wiring. Just for ease of use/maintenence, and incase you want to run 2 pumps, with a surge tank setup. However, you can just use the standard wiring and plug it all in, or use the normal ECU power to trigger a relay. Note that the standard wiring supplies both the earth and power for the fuel pump.
  A lot of external pumps earth themselves if you bolt them directly to something, with like a coil sleeve around it, rather then using the rubber mounted bracket. So all you need to do is then give it ignition switched power. Normally the Blue wire, the white/black stripe wire is an earth, if mounted as I suggested, just tape the end and leave it dangling there, no need to plug it to anything, if you do the fuel pump won't work. Easy. :)


• So, Ecus got power, Fuel Pumps got power... everything should be a go... Triple check fuel setup, engine/gearbox all done up, cambelt ok, etc etc. Fire it up. :D


• It may take a while to kick over, as the fuel rail will need to be primed.



Summary of Wire Colours:

Unfortunately, there are a number of different looms.... coming in a variety of different cars. This caught me out recently.
So... I'm not able to provide a colour list that is all you need. Club4ag have wiring diagrams, but at the end of the day. If you don't know how to work it out, or haven't wired up a motor before, maybe have someone sort it out for you.

PLUG: Nite Parts & Performance Ltd - do plug in play wiring looms, where all you need to do is connect the necessary wires on your car... or, they can completely wire up. Either way, the loom is going to be tidy, and you one less thing to worry about on your transplant/conversion. Good Luck.

Ok, think that's about the lot.. any questions just let us know on the forum. Enjoy the 4AGE power!!
