Re: Remote Control Tach question

Some of the very early control boxes only have a grey signal wire. If you only have a single grey wire-it goes to the S terminal on the tach. In those cases, I prefer wiring the + and - electrical source that drives the other gauges on the dash. Later boxes have a pigtail with three wires, the grey, pink (pos) and black (ground) for connecting the tach. You can decided if you want to hook up the light in the tach.
