Also, if you are crafty, you can use something like your brake light for the temp warning. "You just have to remember". The brake light is already all hooked up. Just tie into the brake switch wire and run it over to the temp or sender.
However, remember you must actually get the correct sender. They MUST be for a lamp and not a gauge.
GM or Ford, can't remember, did this "awhile back," remember? They had an "engine warning lamp" It was branched off to BOTH the temp an oil, one light did two jobs.
