The CTS sensor response is definitely different between Mopar and GM (see www.msefi.com for the exact response curves of each). My CTS is a GM one (with the single blade connector sticking out) that cost about $0.50 at a local junkyard. It fits in a perfect sized hole in my M1 intake directly under the A/C bracket. I simply bent the blade in the direction of where I needed to plug in the CTS signal wire connector. BTW I fabbed up the harness and computer (MegaSquirt) by hand in a few hours so if this redneck can do it w/junkyard parts then surely someone armed w/the power of "Painless Wiring" can do it...
