water temp gauge ?

kenny's 370z

i hooked up a temp fan toggle switch until i can get the uprev fan mod and its working really well eliminating heat related bogging issues.only problem is, it cools so well i can't tell when the thermostat is opening and closing.on that note,can anyone tell me what wires i need to tie into for a water temp gauge so i can see when and when not to turn the fans on by coolant temp ?

ooops.turned out excellent.pics are bad but it looks great in person and the temp is right on the money.temp does run 190-192.when you hammer the throttle from say 6th to 4th from a 70 or 80 roll,the temp almost instantly drops to 180.bad oem rad flow



let the fine tuning of the cooling system begin !

edit;and btw,as you probably already know,the stock temp gauge is as accurate as todays weather man.it straight sucks !
