I just picked up my new to me 1966 last Friday. Fun so far! I ordered a new speedometer (old one didn't work) and started the process of putting it in tonight. It is the Omix model here (https://www.morris4x4center.com/omix-ada-speedometer-cluster-0-90-mph-17206-04.html). When starting to take things apart/put things together, I had some questions: 1) There is a spot to hook up the temp temp to the gauge cluster. When I took the old one off there was nothing connected. I have a separate gauge on the dash for engine temp (I put a picture of it on here, from behind). How do you attach the temperature sending unit to the new gauge? It only has a stud that it looks like you should hook up an electric connector. 2) None of the lights worked in the gauge cluster....some are simply burnt out and some I can get nothing from when testing them. Two that I can pick up voltage on are what I believe to be the amp and oil pressure dummy lights. I also have a separate oil pressure and amp gauge. Thoughts on eliminating the separate gauges? 3) What on my dash is original and what has been added on? I'd like to go back to what was on the original dash....less is more in my mind. 4) There are two switches right next to the tach.....any idea what these may do? I cannot figure it out near did the PO. Forgive some of my terminology here.....I'm new to some things mechanical related, especially when it comes to electrical components!
