what wire do i need to cut to put a tach in my 92 ranger?

 

with a 2.3

 

yeah I dont know either, brown/tan with a yellow line I think

 

I have a 92 2.3 L Ranger too and i spliced the tach wire into the black/yellow wire coming from the bottom plug on the DIS module which i think is between the intake and the brake booster.
