Nuke-E Posted August 20, 2015 Report Share Posted August 20, 2015 Here's a teaser for something I decided to put together after working with Carl on the wiring on his bed after the East Coast Rally a few months ago. Even though there were a lot of splices eliminated, there were still a number of places that it wasn't easy to get everything crimped together (especially ground wires), and the heat shrink connectors Carl was using weren't exactly cheap. Some time later, I was working on a few revisions for the gen-2 headlight wiring harness and getting a few other things ready for my next order, and thought that there might be some interest in putting together something to make lighting up the bed easier. Below is a picture of one of the working prototypes from the manufacturer (a number of changes are still in the works). The way I've laid it out, there are basically 5 pieces: Frame rail section--plugs in to factory 5-pin connector, and runs along frame rail to back center of bed where it meets the frame end section. Connector at forward end to plug in to intermediate side marker light harness (not required, but a good idea), and one at the rear end for connecting to identification and license plate lights. Frame end section--basically a "Y" that splits the 5-pin connector into 2 4-pin connectors, one with ground, tail, reverse and left turn; the other with ground, tail, reverse, and right turn. Side/corner section--where most of the lights plug in, one on each side of the truck. Connects to the frame end section, and has connectors for reverse lights, stop/tail/turn lights, rear side marker light, and rear clearance light. ID light section--plugs in to frame rail section, and has 4 connectors to plug in 3 ID lights, and one license plate light. Intermediate side marker light section--branches out 2 directions from frame rail harness (one for the left side, one for the right) and carries both stop/turn and tail lamp circuits (more on the reasoning here later). In addition to these, there would be an assortment of pigtails (for the clearance/marker lights) and adapters (for the normal 3-pin light connectors). For the reverse and stop, tail, and turn lamps, the harness ends with 3-pin connectors that will plug directly into Truck-Lite's LED tail lamps (the Super44 Fit-n-Forget series with lifetime warranty), or to adapters that go to a normal 3-pin male plug. I didn't want to go directly to the male plug, just because one of those laying loose is asking for a short. Believe it or not, I actually picked this particular connector without knowing about the Fit-n-Forget lights--I can either claim that great minds think alike, or the more likely--dumb luck. In addition to labelling each plug, I also plan to have colored shrink wrap near each plug so that the connections can be made by color as well. If the wires need to pass through a small opening or grommet, the pins can be removed from the plugs without too much difficulty. Obviously, most of you already have lights wired up--this would primarily be something to make new bed builds easier. I'm also trying to make the lighting requirements easier to understand--basically, if there's a plug, there needs to be something plugged in; ideally the harness layout also makes locating things a little more obvious. I'd really appreciate some feedback--both on the design itself, and on whether there's any interest. I'd also be curious if there would be interest in a "package deal" with all of the lights included (and all of the connectors pre-installed on the lights that don't otherwise have them). I want to have a few ready for the rally, but it's still at a point where I can make changes. I don't have a final price from the supplier, but my goal is to be able to offer this for about the same price as all of the wiring and connectors bought at a local parts house.
