I got mine from www.thunderracing.com

What Year Car do you have?

You guys with the OBDII Cars with stock Harnesses can take a little time and re-pin the Back Connectors in the Harness to make them the Primary Sensor Connectors, and then you won't need them..

I did that with my Swap Harness, relocated the O2 Sensor Connectors to the top-side of the Transmission..
