Oil pressure gauge - hotwire harness

Anyone running the hotwire harness here and also have a oil pressure gauge? I have speedhut gauges which came with a pressure sender that fits perfectly in to the existing oil pressure sender spot. However there is a connector as part of the harness which I assume the ECU needs to see. i am running remote lines so is there anywhere else I can put an oil pressure unit or does the ECu not need to see oil pressure?

It's a bit annoying as I want to physically see what my oil pressure is not just have it go to an ecu. I know this was the case with the engine temp sensor so I'm guessing this will be the same.
