with it being a GMT400 i'd need part numbers off it for sure, but the amount of electrical tape, and how it is mounted looks aftermarket for sure.
The red lights are side lights and brake lights here as well. Interesting change in the turn signals though. What do you use as reverse lights?There looks to be a lot of electronics in that wee box!
My 'Burb has it's rear lights wired differently - what were previously reversing lights are now indicators (turn signals) with orange bulbs and the 'red' lights are side lights (first position of light switch) and brake lights. What's in the box looks like more than needed to achieve that change.
