Just wanted to let everyone know that Summit discontinued the RPM switch that most MEVI users are used to. I recently found out as I just installed my MEVI last weekend. So I was left with the upgraded switch from Summit: http://www.summitracing.com/parts/SUM-830449-1/

This switch does work, and it works fantastic! Has dipswitched to select # of cylinders and RPM select is for dummies. lol. The wiring is just like the Harlan switch that was the preferred switch before those were discontinued. If you find the MEVI install writeup on VQPower it has a diagram of how the Harlan is wired. Go by that and you're gold.

So what there are plenty to choose from MSD, or other companies....
