Megajolt-zetec wiring diagram
Hi all,just had my megajolt delivered for my 2.0l blacktop zetec running zx6 bike carbs but am a bit overwhelmed by all the wires! Has anyone made a
wiring diagram for this setup I could take a look at? I don't want to blow it up

This bit is important - you'll need to work out which connections from the TPS on your carbs go to the MJ. All you need is a multimeter to test
them.
quote:
To hook up your throttle position sensor (TPS), disconnect the TPS, and use a digital multi-meter. Switch it to measure resistance. The resistance
between two of the connections will stay the same when the throttle is moved. Find those two - one will be the +5 Vref and the other a ground. The
third is the sense wire to the MegaSquirt® controller. To figure out which wire is the +5 Vref and which is the ground, connect your meter to one of
those two connections and the other to the TPS sense connection.
If you read a high resistance which gets lower as you open the throttle, then disconnected wire is the one which goes to ground, the other one which
had the continuous resistance goes to the +5 Vref from the MegaSquirt® EFI Controller, and the remaining wire is the TPS sense wire.

Thanks mate when I get to a position to wire it all up I'll take that into account. Lewis.
