Giordon Remote Start Car alram

Hi, i wish i hadnt have bought the giordon 686 remote start car alarm, but to late :P

The problem is, its all wqired up except 2 wires, a white one, which the wiring diagram just says "ACC" next to it, the violet wire, i have tried everywhere, and am still confused,

oh and the hand break one is confusing..

When i press the button to start it, it starts, then i press again, and the starter motor stops, the engine runs, this is good, BUT, 3 seconds after, it tries to start it again, and crunches, im asuming this has something to do with the viotlet wire, i have tried it around the HT leads, and have also tried it on the tacho wires on the coil.

i have posted the dieagram showing what im confused about :)

hope you can help!!!!

i have a Ford Fiesta XR2i on a J plate (1992):)

and im in the UK :P i forgot to add that lol

i will try this after the weekend as im away racing all of it :)
