Scotch-Loks, solder joints, Deutsch connectors, DR25, wiring mock-ups, and the wiring tools you actually need when a job goes sideways.
In the first episode of Build Support, Caleb answers your wiring questions from the HPA community, covering the essential tools he’d pack for an emergency harness repair, how much abuse DR25 heat shrink can really take, and the simple method we use to plan harness lengths before cutting expensive wire.
We also dive into wiring loom methodology across major ECU brands like MoTeC, Haltech, Link, Emtron, and FuelTech, and why the fundamentals matter more than memorising every single manufacturer’s quirks.
Then it’s time to rank connector types, from AMP Superseal, Deutsch DT and Deutsch AutoSport connectors through to open-barrel crimps, and more.
To finish things off, we check out Georgii Gavrylenko’s LS-swapped 1982 Porsche 911 SC, a street weapon built with the help of HPA courses, plus a quick workshop update on our C5 Corvette FuelTech wiring and Ando Engineering’s 8HP-swapped Volvo 240 wagon.
