I had mismatched ECU and injectors
So I change ECU ( red ECU and red injectors ) put it all back together and started it up it runs and reverse works but now my display and headlights don't work put my old ECU back in and display still don't work what am I missing?

I think there is a relay that could be your gauge headlite issue. I had an 07 dragon that the head light and gauge wouldnt work until the sled warmed up relay was sticky i guess. On the 07 the relay was located in the front to the left of the pipe above the shock tower.
