Water Temp Elec. Gauge Hook Up.

Whats up guys does anyone have a water temp gauge hooked up to there 4v. I don't know where is a good place to hook it up. I went to a speed shop and they told me i'm going to need something special to hook it up.

I need this because my stock gauge is broken and i'm having cooling problems. Coolant keeps coming out of the tank. The light stays on now for the coolant. I added some and it doesn't want to go away.

I don't want to blow my motor or a head gasket because of this stupid crap.

Don't tell me none of you guys on this forum haven't done this???? This is something you can do for $500s. LOL =)

Well see i'm beginning to think the senser or something is messed up. DAMN IT YOU GOT ME ALL EXCITED THINKING SOMEONE ANSWERED MY QUESTION. "NNoooo i have to fix the coolant problem first." I know this that is why i need a reading somewhere. LOL

Now do you know how to hook up the gauge??? =)
