Hey
The light gets wired through headlight assembly. The end of assembly on the left side slightly above and behind carbon brush is where it connects.
If you go to you tube I believe there is a sentria 2 dissambly and a reassebley video. That's how I got it put back together.
If you take a pic I have a manual I could show you the diagram.
How are you liking the vacuum. I forget how nice the sentria is until I use it. It's a beast . Good luck.
