Brown/white wire, blue wire, what are these?

[Custom/Ten]

Just unsubscribing to some old dead threads and came across this guy. I was so clueless when I first got my truck. I've really learned a lot with everybodys help on here. Just though I'd settle this in case some clueless guy like me comes across this in the future.


The 3 wires in question were parts of my transmission controlled spark which the previous owner had half removed. I removed them all and have had no issues, just made it look a lot cleaner under the hood. Everything I've read on here says tcs never really worked that well which is why most people just removed them.
