Coil wiring question

[Davemate]

I appear to have three wires connected to the coil  ??)


One goes to the dizzy - so that's ok !
One is coming from the loom near the alternator,I converted it over but I didn't touch that side of things
The one which I think is a bit umm, goes off towards the relay thing at the bottom of the pic. I think is the creamy looking wire on the right terminal


I did that maybe a previous owner added an ignition fed live but I don't really know  :X
Anyone know what it could be ?

I've had an explanation from mr Radders, it's the feed for the overdrive,that's what the relay is on the inner wing which is were I think the wire goes to, so tomorrow I'll disconnect it and see if the overdrive solenoid stops working(his suggestion).

So that's probably sorted that out  :)
