electrical guys! i need help bad!

a buddy of mine is a pilot and used to be an aircraft mechanic. he is good at elec. stuff and he is a motorhead as well. anyway,we figured out that since i went from the factory amp gauge to the autometer volt gauge,i have to wire the volt gauge in parallel rather than in series. seems the volt gauge is cutting my amps to everything else. makes sense to me. we had pulled up some diagrams on mymopar.com and comparing the two switches in the column,they are the same,so i hope we have it. we are going jeepin today,so maybe this evening if i feel like it i will mess with it.
