When the park switch input to the 1227730 is grounded, the 1227730 will not need a VSS input. I strongly recommend USING a VSS input to the 1227730. The engine will run without a VSS, when the computer "thinks" the vehicle is in park.

Thanks guys...the street rod currently has a 4000 pulse vss and the 700R4 (shifter) is wired for park and neutral to the ecm.
Just rec'd an email from Intellitronix support, they said their speedos will work with any vss...just needs to be calibrated.
Again...would there be any problem splitting the vss signal to both the ecm and speedo?
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".
