Help identifying incandescent Whelen lightbar from ambulance (with pics)

[casualmaleXL]

Hi all,
I picked up this Whelen lightbar from a government auction today. I'm trying to get it working and was wondering if anyone could help me in identifying it or locating some manuals/wiring diagrams. I'm a complete newbie when it comes to lightbars but I know a bit about wiring. Thanks!

Looks like an early version of the Whelen Advantedge 4500 series. The rounded lenses were replaced in later years but the flatter ones common on the Edge

Definitely looks like it, I also found this: https://www.whelen.com/wp-content/uploads/2020/08/4500_Series_Lightbar.pdf

From these links I found, I'm thinking it's 5000 series:

Are you sure it's not the front side bar not the rear bar, I thought that's how you could tell them apart, rounded in the front flats for the back.
