5.3 swap-stock gauge info

[oldironryan]

I've got an 85 suburban that is getting a 5.3 put in it. Any ideas or direction on getting the coolant temp gauge and/or the volt gauge to work?

Use factory wiring, sensor, and obtain the threaded adapter from summit. Remove large allen key bolt on passenger side head. Install adapter and then install factory 85 sensor. Temp will work.

Sorry to sound ignorant but do you have a part number or actual name? I can't find it...

Here are the part numbers that I bought from Summit. I don't have them yet but have found some people that used them and it works!

ATM-2259
ATM-2277

goes into the pass head where the allen bolt is located.
