Brake led lights blow fuse

Toyota, Tocoma 2014 2 wheel drive.
Had a Trailer light convertor go bad, lost tail lights, brake lights, and blinkers.
Replaced fuses and disconnected convertor, now the brake lights fuse pops when you hold the brake on for a minute, this brings on the abs light and anti slip light. I will try test each light, to see if one has a high amp load and replace if found.

What is the amp load for the Led brake light? Can you change the Leds without replacing the whole tail light?

What parts and information do I need to use the trucks wiring.
Where is a location I can buy the service and repair manuals?
