just run the regular v power plug...........i been running them for years im my car with no issues at all.....plus they're like $2.50 each........very seldom do you get to go fast and be cheap lol
in my lt1 i change em once a month or so....usually they are perfectly fine but i do them any way just for inspection....thats in a race application though...........i have them in my gto and they've been in there prob two years now.....and in my truck over two years now
