Thanks for the tip on Rock Auto, great resource. They have a lot of useful connectors cheap. Unfortunately the crank/can connector options for the newer Hemi plug is still more than the sensor itself. I'll just stick breadboard headers in there for my test stuff and plan on a GM plug or sensor+plug for my Dart update since I can work with pretty much any sensor. The Holley sensor and wiring is also very high price for what it is.
