That's why your gauge isn't working. The temperature sending unit is grounded using the ground from the gauge, not the signal wire. Disconnect that tap and you'll be good to go.

well i did all of it and it did not work still. so i took my sensor out and there was a bunch of gunk or something, and pretty much corroded the sensor. my bro had a sunpro water temp gauge with the coil sensor and gave it to me. i installed it and perfect. it came right on. it looks goofy though with a white face sun pro gauge and two ractive gauges. haha. o well
what is normal temp or what not? the gauge reads around 160ish....

well hopefully it's just the ground then. i will try and change the ground to a different position. i am pretty sure that everything is hooked up correctly. if everything is correct then i am now worried that i have been driving w/ a motor that's been getting too hot!

does everyone else usually read around 145-150???
I can't say. If no one replies here, post in another thread asking. Maybe general protege help/NA Tuning. Mine's just been steady here on that and it's too low on the gauge to be high, so I know it's not over heating. Try moving your ground to the block and try it out that way.

i will try moving my ground to the block and report back. when u say move ground to block. do you mean the ground i have coming from the gauge itself where i have it running to the firewall in the interior? or adding a ground from the sensor to block? can u find any pics or draw an illustration? sorry for being complicated....
Alright, i have yet to do this yet, but, I'm running the Prosport temp sensor and no way is it gonna fit in the parts you have listed. What sensor are you using?
I'm gonna go to homedepot again and swap the stuff I bought for something that will fit. Hopefully I can get to doing it this weekend.

If you wanna hack it, buy one of those adapters pictured above that goes online in the rad hose. If you wanna do it properly, drain the coolant, remove the water neck, and drill and tap it there.

Where the stock sensor is that's the water neck. Hell yes you can do it yourself. Four bolts to remove it.
