As above suggests looking for this?

Some sort of context would be useful!

Wiring up a megajolt system need a 12v positive feed which is still on when turn ignition from on to cranking (ie to start it).

As you are using the coil packs you dont need the +12v switched feed to the original single coil, use that feed which comes from the pair of brown plugs under the dash. This is what I used and worked fine with Megajolt, remember to add in a 5amp fuse though.

Have found the plugs under the dash next to the tunnel (one plug has about 9 pins the other about 5), how do we know which one is the feed?.

Depending on looms (different aged cars have slightly varying wiring) the feed will be in either the smaller or larger plug and it will be the thickest red wire, wire number 2. This feed is switched with ignition and cranking.
