Below are some general instructions for hooking up an electric
speedometer. This connector and these instructions will ONLY be used in
the event that you are utilizing an aftermarket electric speedometer. If your
car does NOT have an electric speedometer, this connection will NOT be
used and should not be plugged onto your dash harness. It is best to
consult the speedometer manufacturer’s instructions if you have any
questions.
