'99 TJ automatic trans filter change - weird wire w/pics

Ok- JP Newb here: first post, just bought my first jeep, and this is the first time doing a lot of my own maintenance. Lot's of firsts...but it's going pretty well so far thanks to this forum, but ran into a question about a wire behind the trans oil filter.

So, I bought a '99 auto Sahara with 103k miles and wanted to do all the suggested maintenance because it didn't come with any service records and just assumed the worst. Today I decided to change out the transmission oil filter and when I finally managed to get the skid plate off and removed the trans oil pan, I was really glad I did. The magnet in the pan was a furry hockey puck covered in sludge. The rest of the oil looked ok, but there were a bunch of metal shavings on the filter and in the pan itself.

But then I ran into something curious:
What is the wire behind the filter and is this where it's supposed to be? I didn't see it in the FSM diagrams or in other pics on the forum and it looked a little out of place. I panicked a bit at first thinking that it was some band, but it just appears to be two wires that connect to a plug on the outside of the transmission. Should I leave it alone or does it need to be re-routed?

Any thoughts are appreciated before I put it back together.

(Sorry for the Mr. Blurrycam pics) Pic of wire with the filter removed.

Don't worry about it, it is supposed to be there. It connects to the locking torque converter solenoid.
