i just finished installing celica cops in my BP+T MS1 v3.0 festiva and now my tach doesnt work. i wired it as per Lazzer408's diagram. its not a waste spark tach so i made a module as per a ms1 in a 323 gtx :
ive tried wiring it to the ms output to the coils the tach output terminals and the (1+4) wire and the (2+3) wire and neither way worked.
any thoughts?

make sure its a ziener and make sure you put it with the stripe facing the over diodes like in the picture:

k...i didnt disconnect the tach circuits at first and i dont think they hurt the coils but it did cause a spark break up issue above 10psi... removed the wires and it revved smoothly to 14psi.
should i remove the 100k ohm resistors from around my diodes?
edit: what spark plugs should i use?

the diode thing didnt work at all... i tried both with and without the pull up and neither one makes the tach move at all. here is my crude little tester i made. i soldiered all the connections together and to the corresponding wires on the car.

I had KLg4 coils on my 323 on the KL and used the same diagram as post earlier by me.
the ziener diode i used from RS was this:
