Coil mistery wire !

I have a wire that is not connected at one end and i'm concerned it should be !!

its a black wire connected to the terminal on the far side of the ignition coil next to the bulk head ( furthest from the front o the car). but the other end is not connected and has a spade connector on it ??

It is coming from the terminal with another black wire which goes back through the bulk head to the cabin.

any ideas where it should go ??

What year/model is your car ?

How many wires does the coil have coming off it that do go somewhere?

What colour are the wires?

Red/Black goes to - Negative side

Green goes to - Negative side

Black goes to the + Positive side

Lilac/White goes to the + Positive side to Pin C15 on series1 fuse box (Pre <1983) Pin D15 on series2 fusebox(Post 1983<)

could be a wire someones put in over the time the cars been on the road,as that side of the coil is a switched 12v…

so someone could have used it to run a relay or whatever for an additional circuit.

If your car runs fine and what not without it dont worry

Hi yeah the engine runs ok, its a 1983 1.8 GTI which I have slowly been bring back to life ( new fuel tank, fuel line, fuel filler neck, new clutch, gear linkage kit, new fuse box, new heater motor, new window wiper motor, new tyres, new wheel bearing, new shocks, springs, brakes, anti roll bar bushes, new steering rack, new manifold & system and loads more…. I wont bore you ! )

this was a small bit that I though might have something to do with my starter motor "running slow" sort of turns over slower than I expect, I have check and cleaned the main earth I was just worried that this should be connected some where.

Thanks

Cheers Snoopy King I will check which wires are where tomorrow.

Thanks

The black wire provides 12 V to the coil, via the starter solenoid during cranking. This is to provide a stronger starting spark. When running, the coil +ve is provided by either a resistor wire, or a ballast resistor connected to the fuse box.
