I originally paid someone to do this work because i really didn't want to tackle it but now it seems they were way in over their head and I have a hacked harness that i need to wire up. Every and I mean everything is removed from the car wire wise. I have to run two wires to the back one for brake light and the other for the fuel pump. It only has the bare necessity wiring in the engine bay:

injectors 1-4 (ID 2000)
Ignition coil 1-4
ignition coil 2-3
Tranny harness
crank angle sensor
cam angle sensor
water temp
radiator fan
TPS
knock sensor
Zeitronix wideband
walbro 255 fuel pump
Jay Racing Bosch 044 external
AEM electronic boost control

I am running speed density so I have:

AEM AIT sensor
Omni 4 bar sensor

I have these extra sensors

Fuel Pressure
Oil Pressure

So my question really is i am told there are two wires from the alternator that is needed Exciter wire and something else... Does anyone one know by chance?

Secondly are the fuel pumps and radiator fans the only thing i need to put on a relay?

Anyone one know who i can talk to that knows a bit about the wiring in our cars. No fuse box in the car. Will run inline fuse holder for ignition coils, fuel pumps and radiator.. I am not sure what else takes a 12V but that will probably share the Ignition fuse.. Sorry if this sounds like rambling but I've been up for quite some time and am ready to hit the wall. Thanks in advance.
