Hey how do you hook up a water temp gauge... Like where do you tap the wire into?

another alternative is to buy a Greddy water coolant adapter to hook up the sender of your gauge

 

Please read my post -

IMHO, drilling/tapping for a water temp gauge install is just a bad idea. The throttle body coolant line is easier to install, gives a better reading, and is quickly and easily reversible.

Hopefully someday people will stop drilling/tapping thermostat housings .

^Agreed. Easy, accurate and inexpensive.

 

Thanks for the link, Dale. Was iffy about tapping into the T-stat...feel more comfy now that I can follow your walkthrough which seems easier and very cost-effective.

 

I bought a long block that had the old drill and tap in the thermostat housing. I had to take it out and JB weld it shut so it would stop leaking.
