Likely you turn signal output was made for non-led bulbs and is overriding the pattern.

i have the same lt on the left side and it will triple flash with the engine running or off and this is what is confusing why just the pass side also i tried to edit the post but i did not see the option

Try swapping them. If it follows the light head then it's the light heads problem. If it stays on the side then it's an input from the vehicle problem.

Is the Pattern wire hooked up to the Power on that one side?

That may be the default pattern? That's how some techs lock in the default pattern permanently.

That's possible. That's why I recommend swapping the lightheads to see 1, how they are wired and 2, if the problem follows the head or remains at the same side.

the pattern wire is disconnected

Again, switch the two lightheads. If the problem follows the lighthead, it's the lighthead. if it stays on that side it is a vehicle issue.

thanks for all the help i tied the turn circuit wire into my trailer plug and the light triple flashes like the other side so it must be a messed up body harness from royal bodies i will trace it down but that will be for another day when it is cooler and slower
