WTD: really simple wiring diagram for megajolt E with zetec engine
bowood14 - 17/1/15 at 06:29 PM

Bearing in mind I'm not a mechanic or electronics engineer Does anyone have a really simple wiring diagram for a megajolt E on a Zetec engine.
So this will be the Megajolt, edis, coil, crankshaft sensor and TPS
I've looked at this but still a little confused!! Doesn't take much to confuse me

Any help gratefully received
Thanks Adrian

Hmm, I would say those diagrams are the best you're going to get. Aside from what they contain, the rest is about where you place the components.

This one is the key one

As a wiring diagram, it doesnt really get any more simple, get it to run on that (ignoring the pip and saw connections for now)

It'll start and run on that, if it does, add the pip and saw

Plug the mj into the pc to check its giving live engine speed datdata etc

Then the throttle position

Take it in steps

Thanks for the advice I will start drawing on a piece of paper and see how it goes.
Update !! done my drawings on A4 paper, measured up the lengths of wire required now to start putting it all together

Nice!
Its pretty straightforward. Have fun

Just watch the connection I f your crank sensor. The engine will not run if the wires are the wrong way round
