If you mean one of those small red & blue panel mount displays, then there are a couple of useful wiring diagrams on eBay including this seller: https://www.ebay.co.uk/itm/353785346516?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=nTY2JwEaSkq&sssrc=2047675&ssuid=R1iToffeQuG&widget_ver=artemis&media=COPY. It sounds like your proposed wiring is OK and you would insert the meter into the negative track feed from the controller. It is also possible to use these without a separate power supply if you want to permanently wire it into your track feed – there is a wiring diagram for this on the link I gave – although I’ve had mixed results doing this. The only thing to bear in mind however you connect it is that polarity is important so it will only work in one direction. I hope this helps.
