Speedhut Gauges

Im getting ready to wire in the gauges and I was looking at the diagram Speedhut sent with.

They ask you to connect the inverter they send with the gauges to the dash lights. I think its odd that you would wire them into the headlight switch so that they can be dimmed from either the headlight dial or the dial connected to the inverter. So Im curious those of you that bought these, did you just connect to the park lights or did you go to the dash light terminal?

Also I find it odd that they have the pointer light separate from the dial light. Seems like they could had saved a extra wire connection if they would had run the pointer light thru the inverter also. Other than that Im very please with them so far!
