You need it because the tail lights are controlled via a "rear illumination ECM" (don't worry, theres a font illumination ECM too). On most cars, the turn signal blinks quickly when extra tail lights are wired in parallel (only with trailer plugged in). On the LS (supposedly), the rear illumination ECM gets unhappy/dies. To avoid this, I'm using PNP transistors to modulate a 12V "hot" signal to the trailer lights, based on the state of the EMC (grounded or open) - but this is all from the diagrams. I need it to warm up outside so I can install it!

Just a heads up, I gave up on the circuit. I found an all-in-one box online and bought it, and plugged it in. All done! It ws something like $50
