Review on 🚦 Smoke High Mount Stop Light Third Brake Light Replacement for Silverado/C10 C/K 1500 2500 3500 and Sierra C/K 1500 2500 3500 1988 to 1998 - Rear Center Cab Top Roof Tail Light Cargo Lamp by Partsam by Brett Kolpack

Like others. 2 stars because I had to cut the plug and hard cable. For small wires, the easiest way for me was to solder them and shrink wrap them. As with the 88-98 Chevy Silverado, this is not required and can simply be replaced with an existing plug. I have 94 K1500. Not sure how waterproof it will be as the back is thin soft plastic and definitely needs to be thicker and more playable to preferably seal the rubber. Like others, use a washer or o-ring with screws to avoid cracking the case. I used two internal bolts from an old lantern as it has a wider washer head. **You must wire the following for proper operation**: Black and Yellow light to truck Black Red light to truck Yellow White light to truck Red Do not use white for truck. Months of rain and snow to see if it's well sealed.
