Hi guys and girls I'm wondering if someone who could help me out here, I'm currently building a gf8 budget rally car. So far I have fully stripped the interior gutted the inside of the doors boot bonet and all of the Heating & Air conditioning unit from behind the dash I've added Lexon windows and 8 Point roll cage bucket seats and adjustable suspension. I have a window washer bottle behind the driver's seat with sprayers on to the intercooler a surge tank in the boot bed by the original fuel pump and a Bosch 044 fuel pump after the surge tank I have got rotated intake manifold front mount intercooler oil cooler td06 turbo unequal length headers Turbosmart wastegate some pink top feed injectors from a later model STI.
Now here is my problem, AI am a bit lost now that has come to the electrical part of the project. I have a what you probably call older V5/6 G4 plugin link ecu which did run the car fine until I removed the entire wiring loom. I would really like to move the battery to the boot, and from what I am learning so far the power from this goes to a relay box and into a fuse box, I think I understand how that will work, but what I'm not sure on is what I should be powering via the ECU or which sensors need a direct feed. Or is this even possible to do with a plug-in ECU? I looked up the link website and downloaded the manual for the G4 Plus but I couldn't find one for the older G4. Unfortunately I was a little bit to snip happy with the wire cutters on the original loom so that is pretty much toast lol.
Anyway I'm sure there's a bunch of people on here with some hints tips and ideas to make this project a little bit easier, and any help would be greatly appreciated.
