I installed a set of electronic GReddy gauges yesterday (boost/egt). I connected both gauges on the same OEM boost gauge connection for Ilumination and Ground in order to be able to dim them with the stock dimmer. After everything was complete, I tried to dimm that gauges but they lost power or even turn off if dimmed all the way.

I have connected alll my gauges on this connection and never had such problem.

I've researched the problem and found a solution, now, the solution involved creating a circuit. My only questions is, the cercuit that was created was to solve the dimming problem and the dimming backwards as well. I only have the dimming problem, not the dimming backwards problem. Will this circuit work or will it make the guages dimm in reverse?
