Rev counter

So do the wires just go onto the plug that connects the edis to the coilpack?

Basically, yes!

You have a pm by the way

i have megajolt on my car and am using megajolt.
on my megajolt, one of the wires says tacho out. think its a blue wire.
i connected this to my rev counter and it works on tickover, but when i rev it, it goes to zero.
i rang etb up and they said i need to connector a 1k ohm resistor or maybe diode (cant remember now) between battery and the blue wire.
i have bought the part from maplins but havent fitted yet, mainly because i dont know how to. its just a piece of thin wire with a thing in middle. not sure how to connect this to battery and wire.
dont know if you have this wire but maybe able to wire your rev counter this way if you know what you doing.
if not, someone else may tell us how to do it

Thanks Bob, that passion ford picture confirms what I thought I'm gonna have a go at making the loom bit with diodes as they only cost £2 off fleabay for enough to make 10 looms so if anyone else wants one let me know

looking at that simple little circuit using two diodes and a zenner its converting the two signels from each coil (4 cyl wasted spark is two coils) to a single coil and dizzy type signel to run a std tacho

Thats the general idea!
