From Idiot lights to Gauges. Couple Q's

[dracko]

Hey guys, got my dash cluster with gauges in the mail today! cleaned it up a bit and now I think its ready for install. Heres a couple pics....because pics make every thread better.

Before:


After:


I'd like to install it tonight but wondering about a couple things. Can I just plug the harness from this new cluster into the truck wiring harness without any mods?

Also, i'm gonna go grab a new temp sending unit for the gauge, but will I also need a different wire as well? or will the old wire from the idiot light work?

Any other info is appreciated...my first time messin with one of these clusters and I am hoping to avoid buggering it up.

thanks.
