Microsquirt & MSD MC-4

Hi Guys,

Just a quick question, I'm in the middle of wiring up a microsquirt fuel only install with an MSD MC-4 ignition.

The ignition kit grabs the crank position from a Dyna Pro crank trigger.

Question is, where is the best place for the microsquirt to pick up it's signal?

Can/Should i use the same crank trigger as the MSD?

Can/Should i pick up off the coils?

Can/Should i pick up of the factory hayabusa crank sensor?

I don't know if it helps but,

Here is the wiring diagram for the MSD

And here is the factory wiring diagram.

Thanks Again in advance

The gray tach output wire is probably the best choice.

Thanks matt, Seeing as the tach outsput is square wave, am i right in that would go to the OPTIN+ and then earth the OPTIN- ?

That's what I'd try first. Should work with most setups.
