Well got the manual pedal fitted today and the cable run, the movement is realy smooth and pedal position is almost exactly the same as the old pedal.
I have also trimmed the front panel, moved the standard rad forward and started to remove the original wiring, im not sure whether to bag and tuck it out the way or cut and cap all the cables then tuck them back into the loom covering.
Plan is to have a rubber mounted plate where the battery originaly sat with both the original and aftermarket ecu mounted on it.
