ELECTRICAL ISSUES , 1997 CHEVY SILVERADO EXTRA CAB REGENCY CONVERSION

What is your question?

Great truck but I am having some electrical issues now, sitting on about 125,000 miles and lately I cannot get the day running heading lights to work, the outside air temp indicator co-located in the rear view mirrow quit working a long time ago, had numerous issues with the brake light switch burning out but discovered that these brake light switches can be installed upside down and will fit and work for a while even when installed improperly. I just don't know for sure about this truck, it was a custom conversion truck finished up by REGENCY of FORT WORTH, TEXAS and although they are still in business, I don't know that I would ever buy one again. I just have had too many issues with the truck being a GM product and I believe the cutting and splicing of the original OEM wire harness by REGENCY to accomodate the accessories that they install in the truck tends to ruin the factory wire harness and how everything electrical works. I love the truck on the road, it looks great going down the road, but the electrical stuff is crazy !!!
