1. One pin on the cap goes to earth.

2. Cut your green wire and join one end to one of the gearbox wires and the other to the other one. It's just a switch.

3. Yes.

4. Can't see why not.

Hope that makes sense and helps a little.

Ignore the middle contact, wie one of the outers to earth and the other to the earth side of the warning light.

i dont quite understand (probably obvious)
my loom has the single green wire dedicated for reverse switch. one side is at rear for light itself and then other side just leads out of loom to connect to reverse switch

with regards to cap, does it matter which side connects to where?
thanks
steve

Steve,

I,m not that good with electrics but from your description of the wire colour going to the reverse switch on the gearbox................is your loom a Premier Wiring Loom?

If so then I have the same loom, might be able to help if so.

cheers
andy

Ah right, connect that to one wire on the gearbox, and connect the other gearbox wire to 12v ignition live.

You can mount the megajolt in the engine bay but on a 7 the engine bay gets much hotter than a conventional car, the EDIS is known for not liking the heat, and as EDIS and jolt need to be connected with signal shielded cable I found mounting both under the dash/scuttle worked better.
Attaching a laptop for data logging is also easier with the jolt in the car
