How hard would this be to install? i would like to have it come on when the key is on? anyone ever installed one like this?

Cut hold, install 2 wires, (one to ground and one to OFF side of ignition switch,) and you're done! Same principal as my LED gauge.

First and very important... you must own a quality voltmeter so you can test your sparky! Harbor Freight has them as low as $3 so money shouldn't be an issue. If you have one then test BOTH leads off the switch with the key on and off. Key OFF and power means the HOT side. Key OFF and no power means the OFF side of the key switch unless key is turned ON. Use a plastic wire crimp to attach to current wire without cutting if possible. To make sure you have a quality ground go ahead and use the 4 battery if you want or find one inside the dash if available.

You'll be using the existing attached/coming with your new gauge most likely... if it doesn't have wiring then 16 should be fine since you're only using it for the gauge itself. May I ask how comfortable you are with wiring and the basics involved? The reason I say this is that it may be better for you to just do the #4 battery as ground instead of trying to follow what wire is for what.

Well i not real comfortable when it comes to that i was just not sure what the best or easest way is i think it does not have wires so i will get some 16 gauge and run it to the off swich on the key. Then run a new wire to the negitve on the number 4 battery. That sounds the best was not sure if i found a good ground under dash if that work to save wire. I might just goto number 4 battery. What is best way to hook to to battery ? Thanks for your help

If you can find inside your dash, the #4 battery lead used for your headlight assembly that's located in the headlight harness itself... that would be just find to clip into for the negative. But you know what happens when you don't test for polarity first don't you...
