fvs2000

Hello,

I just bought a 2001 s2000 and I was wondering if any knows what is the signal wire on the coil on plug to which I can connect an MSD RPM window switch. I am planning on installing nitrous and would like to install and RPM window switch to ensure Nitrous is only run between 3500 and 7500 RPM.

I have a mustang mach 1 with individual (distributed) coil on plugs. In that car you have individual signal wires going from the ECU to each coil on plug, so i was able to splice one of coil on plug cables coming from the ECU harness and connect it to the RPM window switch which reads the RPMs. Does anybody know how the S2000 coil on plug system work and where could i plug such RPM window switch?

Any help is greatly appreciated.

Thanks
