Hi Gordon........I removed it from my car once I was satisfied that I didn't have an overheating problem and I was done testing out other questions I had. I did have it connected to all four cyls. After about15 months I removed all of it because I didn't like having the gauges hanging under the dash in a little two gauge bracket. I have a Dakota Digital Oil Temp Gauge and senders too if anyone wants that as well. At one time I had 4 oil temp senders plugged into my engine as well. Even a couple on the inlet and outlet side of the stock oil cooler inside of the fan shroud ! Interesting data came out of that little venture. I think it's posted here somewhere.
John............if you have two holes for gauges to plug up in your dash, these may do the trick for you and the info provided would be useful too............Bruce
P.S. Don't forget to use your Manometer when ever possible !!! Ha Ha !! You "Wing Nuts" know who you are.
