The item in my kit

I bought Haisstronica Heat-Shrink Butt Connectors as part of my camper van equipment.

My wiring purchases include crimp connectors as well as the solder-seal splices recorded in the roof diary. This assortment represents the crimp-and-shrink method within that broader kit.

Where it fits my build

I brought the roof light wires and camera cables into a PVC conduit layout. That work included drilled enclosures, threaded fittings, cable glands, solder-seal splices and grouped wiring.

During the small-box stage, I drilled for a male PVC fitting and used a fitting inside as a retaining nut. I routed the camera cable through a gland into a tee and brought the light-wire groups toward the van entry.

My build notes

The wiring project was a sequence of individual connections and routes. The photographs show the intermediate stages, including open boxes and wrapped wire groups, before the remaining covers and conduit joints were finished.

I built the cable route a section at a time, bringing local connections into the larger conduit system.

Alternative products

Two alternatives to compare

Wirefy offers another heat-shrink butt-connector selection. The Nilight assortment adds terminal shapes beyond straight splices.

These butt-splice connectors join wire ends through a crimped metal barrel. Their heat-shrink outer sleeves cover the connection after crimping.
