No wiring to inhibitor switch on gearbox

Hi I've opened the inside dash took out carpets but can't find the 3 pin plug that fits on the inhibitor switch mounted on the gearbox, however I did find a green and a blue wire which wen I touch together the reverse light comes on, so reverse is sorted, my only worry is I need to trace n find and reconnect the starting wire to switch, cos now the car starts in D, R, 1,2, if you can help me with the exact colour of the wire from the inhibitor switch to where it connected inside dash area, and from there off, thank you for your help much appreciated, Godbless
