MSD 8950 activated switch, and adjustable RPM selector module MSD 8670. The selector has a range of 3000 to 5200, and depending on how you wire the switch you can adjust the range up or down. I was going to use it for a shift light but never got to it.
You can see instructions for the switch here: http://www.msdignition.com/Products/...ed_Switch.aspx
Both are unused but don't come in their original packaging or with paper instructions. I can send pics if needed.
100 for both, shipping included in conus.
