Wiring Question

[Dancol]

Hello All,
I am new to the site. Drive an STI type R Ver. 6. Have fitted a Power FC ecu to car and it seems to be running fine but there was a piggy back fuel and ignition controller in the car along with the standard ecu. As far as I can tell the piggy back yoke wasn't doing anything as the main part of the loom wasn't plugged in to it. But there were 5 wires running out seperate to the main ecu loom to a sensor under the intercooler and another one on  a unit mounted onto the front of the unit that the 4 spark plug leads plug into. Question is how were these sensors originally wired in?
Were they always on a separate loom or should they be connected to the ecu on the main loom of wires? Any help would be greatly appreciated.
Thanks Daniel

I would really recomend you get some1 to look at that wiring set up..
its impossible for anyone to know without seeing it.. i would will through a guess at it do.. the wires going under intercooler are maybe going to knock sensor and maybe ones going to coil pack are for an adjustable rev limiter like BEE-R limiter.. which can be used as lauch control, adjusting your rev limit and causing cool backfires and flame throwing exhibitions
you be best getting it checked out and possibly all removed if not sure and all wiring eturned to factory spec.. that is the worst of getting a car which someone else has modified.. you just dont know if its right or not..
