this is how I did the taillights I stated with the stock housings
and used a taillight harness out off a 2009 Chevy Silverado because I had a few hanging around at work which is a Chevy dealer haha, but the problem I had is they do
Bake
Revers
Brake instead of
BBR which is what I needed so I rewired it
next I had to come up with a way to make the revers light not hit the lens so I modified the hole and to part epoxied it in like the other too but made it inset so the bulb would clear
and here is how it looked after all the work
and the clearance with the lens on
and here is the running light on much better seems how come it looks like the brake light is on
