I want to thank Neil and Marty for helping me get the problem solved. Thanks Marty for the gauges. Thanks everyone who answered the post as well. One of my problems was something I did. I never centered the gauge in the cluster. The post was touching the back of the cluster causing a ground. I read about this on Mustang Monthly's website in the archives. And when I checked it sure enough that was the problem. I bought a new CVR and when I installed it it was sending out too many volts and burned up the temperature gauge. I bought a solid state with the help of Neil and everything went well. Had some more trial and error installing it, but got it going. All is well except for the vacuum lines, but printed that thread and now I am going back in the shed to get it straight.
