Aftermarket water temp unit

Guys I was wondering where the best place is anyone has found to install the sending unit for an additonal temp gauge? I want the factory one to still work. Thanks guys.

Go down to you local auto speed shop, if you don't have one, go to Jeg or any of the on line speed parts houses.

I already have the unit. I didn't want to diconect the factory one. Didn't know if that was an option? Thanks

Pull the factory sending unit, and put a tee in. Then you can have both, just try to bleed all of the air out...
