Good afternoon,

I have managed to wire the live, clock and earth wire into the car but how do I attach the RPM input? the diagram attached HERE shows the RPM input cable but I'm confused to as what it means, could you please help?

Thanks everyone

Does it need to be spliced in or just wrapped over the HT lead?

The diagram says "either one"

I think that you either...

Connect to the + terminal on the low tension side of the coil

OR

Wrap a 3 to 5 turns around the High Tension lead coming out of the coil

If you are using the wrap method

Definitely just wrap NO splice, it just works like an aerial and picks up the change in magnetic field created around the lead

Cheers, thank you

The Acewell diagram is not great, it should EITHER be connected to the switched side of the coil (normally negative, NOT usually +ve as shown in the diagram), OR can be wrapped several times around an H.T. lead (most definitely NOT spliced!!!) & used as an inductive pickup. What it also doesn't show is that there is a 1 meg ohm resistor included in the pack, if you have any instability on RPM reading, usually will show up either at idle or at high revs if there's going to be any instability, then just add the resistor in series & that will "damp" the signal down & give a stable reading
