Engine codes everywhere!!!!!

[Waterloo]

When I installed the two extra gauges on my dash, in my 08 ProStar, I tapped into dimmer line for the gauge lights, on edit "not at the panel, but from the dimmer switch itself". For power and ground, I used a fused line off of the ignition side of the fuse block in its own spot in the panel. I bought the metal wire clips that snap in the fuse block at the International dealer. I have no issues with codes. I grounded to the chassis.
