Removing Redundant Wires

[brainbug007]

Now that I've got my engine running I've started on removing all the redunant wires from the loom. What should I do with the wires that go from the original ecu to the edis? Will these just get plugged into the megajolt and don't need moving from the edis pins or will it be different pins for the edis to megajolt and they just need removing for now? I also found that I have to wires coming from the instrument cluster connection that just went to plugs which had nothing plugged into them on my loom. Any ideas what these would be for? I'm thinking one or both could the the rev counter as my original cluster didn't have a rev counter.
