does a 88 turbo have a speed signal wire? please assist

 

haha mine is not hook up ,... i duuno either, now i other have the timer and batt volt...help help

 

on mine i dind't even hook that up, I just hooked up the timer and the ebrake line. Mine is out of site where you couldn't see the thing anyway. SO there was no need for it all. Mine does tell the voltage though, but again, not worth bending down to look at it.
