Thanks for all help Everyone. I tried a few different things but could not fix the problem of the trailer lights all blinking (marker lights and all) whenever I used the truck blinkers while hooked up to the TT. I ended up removing the led bulbs I put on the truck 1 by 1. I started with the front truck marker lights and worked my way to the back brake truck lights. When I removed the truck brake light leds and replaced them with the original incandescent brake lights the trailer lights now acted normal. I don't really get it but I guess I'll just leave it like that. Thanks again and I hope this helps someone else.
