hi
can some one tell me what the vss does for the tpi's , what happens if u use it or dont ? who makes the conecctors for a cable style spedo ?
thanks chad

It tells the computer when the lock up the torque converter if using a lock up style converter. I think it also does something for the emissions. When I put the TPI in my 86 Monte, I was able to use the VSS that is built into the speedometer. I used a Howell harness that had the connector to work with the existing instrument panel harness in the car. Try contacting John Spears at www.speartech.com, he will be able to help you figure it out.
