Can I use my keyed ignition on my Qulbix to switch the display on and off?

My Qulbix DIY frame has an SVMC 72150 and a CT22 display. The display has to be wired directly to the battery so it can display the battery level. There's no on/off switch on the display though, so unless you run the power through a switch it would just be on all the time.

The keyed ignition mainly controls the controller, turning it on and off. You run a wire from the positive battery terminal to the ignition, and then back to the controller's ignition wire.

What I'm wondering is if I can also go ahead and wire the display into the keyed ignition, so that the ignition will turn on both the display and the controller at the same time. The contacts in the ignition are pretty beefy, so I'm thinking it can probably handle the current.

I just want to make sure that wiring it up this way won't inadvertently send power somewhere it's not supposed to go. I can't see any issues with it myself but thought I would ask before doing it.
 
The wiring diagrams that I have seen for this display show the yellow wire permanently connected to the battery positive so the display doesn’t lose it’s memory and the red wire connected to the battery positive via an ignition switch to turn it on and off.

(y)Yup. Red should go to the switch orange ignition wire so it shuts off when the controller is shut off.

Oh okay, that makes sense now. I was using the "switched" wiring, and it looks like I should be using the other option with the yellow wire.

While I have your attention, do you know if this thing outputs 12v power for the lights, or are those just LED indicators that you run your light system through?
 
You will need a dc to dc converter and probably a bunch of relays for the lights and indicators, together with switches. The CT22 display just contains the led dashboard lights for low beam, high beam, left and right indicators. And also LEDs for a the 3 speed switch.
