how do you guys usually hook up your autometer electrical water temp gauge? i heard that you can place it where the two characoal canister vacumn lines run to the thermostat housing and just remove the canister...? does the sender actually fit...? will the stock gauge still work if i do this? the autometer came with two fittings and a sender? am i suppose to get a 18 guage wire and hook that up the sender? any pics would be great
