Engine wiring Loom

Connectors There are many ways of doing this. I chose to solder wires onto the exising ones and use heat-shrink to cover the joints. You could also dismantle each connector and solder new pins onto your wires.

Finished loom I covered the loom in non-adhesive loom tape, both to hold all the wires together and because it looks nicer than having tham all scattered about.

Wiring Diagram Here's how I wired it all together.

Testing the loom Just to check I wasn't going to melt anything I decided to plug it all together on the bench. All went well and nothing was smoking, which is nice.

Tiger Tacho The tacho in my Tiger didn't work when connected to the Megajolt output. The solution was to connect it to the tacho out of the Ford EDIS module. This is the pin between the 2 coil outputs.
