Im installing a digital tach and I need to know where the green wire goes to get the tach signal....anyone know?

 

trailing coil.

 

any general info on where it might be? my car has a 1J

 

What? Trail coil is the coil closet to the firewall on the driverside fender wall. Behind the strut tower.

 

ya but i doubt mine is there, as i said before no rotary...

 

Lol.....

When you think you have heard everything!

 

so why are you asking us? there should be a yellow wire by where your trailing coil would have plugged into up over by the clutch reservoir.

 

Unless your original tach is wired up, most likely we'll be unable to help as this information is very swap specific. It would depend upon your year/engine, EMS, ignition setup/etc. All of this could be different given the swap done and we'd have no realistic way of knowing how it was done. If it's a straight swap using an original harness/ECU combination that matches the engine it'd be easier to track down a forum for a car the engine originated from and look on there. Typically you can just pull in signal from the coil triggers, or often from the ECU itself and be fine.

 

so yeah, i have this amazing looking peanutbutter sammich but i dont know where the pickles are.

 

Check behind the freezer...



for your pickles.

 

well i was told by one of you rotary retards that i could connect it to the wire running to the stock tach, but i guess he had downs like the rest of you..... peace gumps

 

The fact that the stock tach is hooked up to a useful source should've pretty much been required information in the original post, as well as the engine swap. As with most anything, the more details you provide it's usually easier to provide an answer.

It's the age old 'Do you have that one movie with that one guy who did that thing last summer?' Not very effective to leave out the details.

In any event, you want the yellow/blue wire, which can be either sourced behind the cluster, or also at the trailing coil's original location. (right behind the drivers strut tower)

 

finally a post not concerning things soaked in vinegar, thank you
