I could see that being an issue. I have heard mixed information when it comes to positive apply vs. negative apply for the brake circuit and LS swaps.

If you are going to use LED tail-lamps, use the digital flashers someone posted above. If you have trouble with the turn signals flashing too fast or not at all, add a load resistor. If your having trouble with the torque converter after all this and you have verified it in a scanner, then add a relay with pull-up/pull-down resistors depending on your situation.
