Wiring harnesses, engineered without compromise.
We build wiring harnesses for motorsport, restomod and low-volume engineering programs. Exclusively with TE Spec55. Concentrically twisted as standard.
Only Spec55. No exceptions.
TE Spec55 is the standard for motorsport and military wiring. We use nothing else — not just the wire, but the complete Spec55-family ecosystem. Tapes, heat shrink, connectors, boots: all qualified, all consistent, all built to the same specification as the wire they protect.
Every section, concentrically twisted.
Concentric twisting packs the wires into tight, repeatable, symmetric layers. The result is lighter, quieter, and more predictable than conventional bundled harnesses. We design for it from the first pin-out — not as a finishing step, but as the starting principle.
Engineered before it’s built.
Every harness starts as a drawing. Pin-outs, routing, cross-sections, lengths — all calculated and documented before a wire is cut. Nothing is improvised on the bench. Nothing is guessed.
Drawings, BOM, traceability — yours to keep.
Every harness ships with a complete documentation package: engineering drawings, wire-by-wire BOM, and traceability back to the materials used. If you need to rebuild, extend, or audit it years from now, you have everything.
Tested before it leaves.
Every harness is tested with dedicated equipment before it ships: continuity, insulation integrity, and correct routing per the drawing. The test report goes in the documentation pack.
A small team. A direct line.
Carrot Wiring Solutions is deliberately small. You talk to the person building your harness, not a project manager. That means decisions happen fast, changes are easy, and nothing gets lost in translation.
