The 12 pin connector I use is also rated for outdoor, waterproof applications. There was one person that had some water get inside the box. The only way I can imagine that it got in there would be if the electrical connector was facing up and rain water was allowed to pool on the connector and then as the enclosure was exposed to expansion and contraction, heating and cooling cycles in the engine compartment, some moisture was drawn in around the wires. So word to the wise, try to keep the electrical connector at a downward angle to shed water rather than collect it. I also pressure test each unit once it's assembled. If anyone else has had any issues like this, please let me know so I can address it and maintain QC.
Previously I was using two different control boxes for 3rd and 4th gen trucks, but now with this smaller enclosure... one size fits all.
