what is the proper way to hardwire from a cigy lighter to the fuse box. Ive always just spliced. butmy GPS and it draws to much power and the adapter is complex(it has like circuit boards inside=way beyond me) and i cant just break into it

 

you need to find a +12v switched fuse and run a wire to it. How much is your GPS drawing?

 

umm, on the adapter it says:
input: 10-30V, 1.3 A MAX
output: 5V, 2 A.

Its possible that i could have just blown the adapter when atempting to hardwire, instead of it drawing to much power. Regardless my cigy adapter is broken and will not work in a normal cigarette lighter plug.

 

there is normally a fuse inside of the tip of the adaptor.

 

I know that, but the insides of the GPS adaptor is friggin gnarly. Its got like circuit boards and wire coils and electrical junk, although there is a fuse, hmmm....
