What does a mitsi tach interface look like?

[thegreatestben]

Apparently I need one to get my tachometer in the mr2 to work with the link.

What does it look like and where in the car is it located?

[3T-Rona]

on the coil/ignitor bracket, on older galants, got a few if u want me to dig one out

[thegreatestben]

Hmm, must be on the coil bracket on the galant I pinched the ignitor and bracket from. Can you take a pic of one for me?
I'll just go get one from pick a part.

Its a little square black plastic box, says Interface on it, or tacho, one of those I cant remember. About 40mmx40mm

Do I connect that to the tach wire on the ignitor, then from the interface to the ign wire?

[Bazda]

The interface has 2 input wires and 1 output.

They are designed to run with twin coil setups, so each 2x '-'ve off the coils to the interface 'in' I think its labelled, then 'out' to tacho '-'ve

Oh ok, Just I am using mitsi twin post coils and matching ignitor.
And the ignitor has:

IB1
IB1
OC1
OC2
12v in
GND
Tach

Seems strange it would have a tach wire and then just use the -ve signals?

That igniter has the tacho interface built into it

the GND will be earthed to make the igniter part work
Feed ign 12V +ve to the 12v in and you will get the correct signal out of the tach terminal to drive a normla coil -ve driven tacho.

Mad.

Seems like I just need to connect one wire in that case.
My face right now
