how to wire the tach signal with toyota COP's when running sequential(1 @ a time)
what diodes/reisistors/compacitors extra are needed & where.

thanks in advance
I wired the tach wire on each coil together to the factory tach wire. No diodes/resistors/capacitors needed.

I figured the factory tach wants to see 4 "pulses" each engine cycle.

Yeah they should, unless my wiring got switched around at some point with may have happened. Those settings match however my wiring is which I am pretty sure is correct but use at your own risk.

I am running the 10000uf capacitor between the power and ground too.
How many capacitors are you running? just one? 2? 4?

2 in parallel would really be 20000 uF.
