HELP! 2007/2008 Chevy Tahoe Transmission Wiring Harness Problem

[vfrpilot2017]

PLEASE HELP!

 

Just swapped a new engine into my 2007 Chevy Tahoe. The engine is a identical 5.3 but it's from a 2008 Silverado. Everything matched perfectly until I got to the transmission wiring. The new engines harness only has a few plugs compared to my old wiring harness. I cut the old wiring harness at the firewall when I pulled the old engine.....now what do I do?

 

I can't fine where two of the plugs go from the new engine at the transmission. I was wondering if they have a additional piece that gets added to the 2008 one?

 

I'm dying over here. I worked so hard putting this motor in and now I find this.
