3157 to 3 wire LED

I recently posted in the 1st gen forum but thought I may have better luck here. I purchased poison spyder's three wire 3/4" led that have a 50% power (indicator/parking light) wire, 100% power for turn signal wire, and a ground wire. I cut the wires to the 3157 bulb in my parking/turn signal lights on my 94 Navajo and wired them into the respected wires on the LED and changed the flasher and only the turn signal works. If I disconnect the turn signal it will work as an indicator but as soon as the turn signal is connected the indicator feature will not work.
Any advice would be appreciated!

Thanks
