piece of piss mate, you need to throw an earth to the sensors and a feed wire to the ecu, thatt's the air temp and coolant sensor, crank position sensor needs a screened cable, earth one wire and signal wire to ecu.
injectors need a wire from the driver from ecu to one pin and live feed to the other, you can use batch firing where 1+2 and 3+4 fire together each cylce or sequential which is a little rare in use due to the complexity.
coil can be driven directly off the ecu, so forget edis as it's crap in comparisson. that's two wires from ecu and a live feed to the centre pin of the coil.
then you've got the throttle position sensor which is only three wires, 12v, 5v and earth IIRC.
just idle valve after that and you can chose how to control that, only one wire from ecu and one live wire to it.
lambda sensor, wideband recommended, still only one wire to ecu though.
pretty much it to be honest.
if you've not done it before you'll make mistakes and probably hit a brick wall, remember getting it started is the hardest bit, but with a little practise it's pretty easy.
