LT-10s Tach Output
 

I recentlly installed the LT-10s version but it comes with a LT-8s manual. I have not been able to identify the Tach Output signal. Anyone knows?


could I just jump the signal from any ignition output?


thx!!!!

tacho output should have been the blue/grey wire on the main plug,

thx Dale,,,

that's what I though but is not working. Maybe I'm using the wrong stock tach input? Isn't it the Yellow/Green wire? (FD3S '94)


Also, I wrote to Tim Possingham [tim@microtechefi.com] and this is what he told me:


"The blue/white wire is the tach out off the Microtech. If your using stock coils then there is a tach out off the stock module.
Regards, Tim."


... and now what!!!?

Why not just pick the signal from the - side of the trailing coil/coils?

Yeap, I'll do that but would like to have it like it should be to avoid more cable routings. BTW I still need to know if I'm picking the right stock tach input (Y/G)...


Does anyone knows which is color of the stock tach input (FD3S)?
