This has been on my shelf for around 15 years or so I can't remember. We put new engine in my 89 Comanche and replaced the CPS during the change as the old one got busted. I am pretty sure I used one from the Jeep dealer. Well the new engine would not run we messed with every sensor and finally found broken wire in the engine harness. During all this I pulled the new sensor I put in and replaced with the old one I knew was good. The Comanche is gone now and I am cleaning out and I am sure if this is Factory someone would want it was only in the truck A few days. It actually says RENIX on it.
