Tacho feed from coil- mk3 abf

Hi Folks,

Newbie here- am the final stages of getting an ABf install in a t25…

am trying to workout how to hook the green wire for the tacho signal on the ABF loom onto the ignition coil.

my understanding is a need to solder on a connection on one or other side under the little flap on the bottom of the coil… is this correct? If so how do I identify which side?

Or am I completely off track?

 

We did this for MK3 AGG into MK2. This is where we needed to solder the wire.

 

Does the abf computer have an output for the tacho?
I make amplifiers so the original tacho works with the signal

 

Thanks Phil! Perfect

 

Thanks man! The original setup was on a digijet computer so it should just swap over. If it’s not right I’ll be sure to say hi.
