possible cock up!

[rpjg1975]

Have been having a play with my electrics (donor loom from j reg 1.8 cvh sierra) and have succeeded in getting the immobilisor which was already fitted flashing, and the small black relay in the donor fusebox clicking when I turn the ignition on. I don't however get any ignition lights. I think I have the main earths fixed (although not the ones to the lights) but have found a white plug coming from the ford little black box with nothing plugged into it and no spare plugs to be seen (3 brown/yellow wires, 1 white/black, 1 yellow/black and 1 red/yellow wires going to it). Im thinking I must have snipped it off when removing the loom by mistake?

Could this be my problem and if so how can I fix it? And if not has anyone got any bright ideas what the issue could be? I still have the bits I removed from the donor loom so have probably still got the plug if it helps?

If not then I'm up a creek without a paddle!

Help........

Cheers
