TPI SBC vss and adding an electrical speedo

[EDZIP]

VSS signals are usually AC sine wave signals. Splitting one VSS output into TWO separate signals will work. Usually two wires sets will be required, one set of two wires going to the computer, and one set of two wires going to the speedometer. Sometimes using two wire sets will cancel out the VSS signal, so no signal is going to either the computer or speedometer. If that happens, reverse the + / - on ONE set of the wire sets, keeping the VSS AC sine wave signal "In Phase".

Thank You...may be a few weeks before I get to this...but at least I have a direction now!
