Thanks in advance for you response

Didn't I already answer this?????

Not sure if anyone would know how the BCM will react to the LEDs since GM never tested for this since the H3 was never designed to LED taillights. My suggestion is connect them and see what happens. If required, slap in the correct resistor load.
The load on those large resistors is higher than normal I believe, but it will be hit and miss for the first person.
I will tell you this, the LED lights used on the Cadillacs, have a complex circuit board installed in the light assemblies for the LEDs.
