Hi guys I'm about to get some new after market gauge for my DC5R and I want to install the Gauges myself Just got a few questions I'm not too sure about

ground. what does ground mean and where do I connect that up too and do i need a adapter or anything ? I tried finding more info about it and there was something about I should connect it up to a alternator screw or something ?

also what extension wires can i use if the gauge wires are not long enough ?

I'll be getting a water temp and oil temp gauge.

and where would i connect the rest of the wires too

power supply and light dimming ect. can i just connect the wires into the fuse box ?


I know what to do with the water temp I'll be getting a adapter and connecting that through my radiator hose.
but regarding the oil temp do i hook that into where the engine oil draining screw is? or where do I hook that into ? and do I need any adapters ?



these are the gauges ill be buying
