Custom Wire Harness Automotive

Note: All specifications are customizable based on vehicle type, application, and environmental requirements.

1. High-Temperature XLPE Insulation (125°C)
Engine compartments routinely exceed 100°C near exhaust manifolds and turbochargers. PVC wire (80°C) degrades and cracks. Cross-linked polyethylene (GXL/TXL/SXL) withstands 125°C continuous. Benefit: Harness lasts the life of the vehicle, no mid-life brittle failure.

2. Multiple Wire Grades for Different Zones

• TXL (thin wall): Lightweight, tight bend radius - ideal for instrument panels and door harnesses
• GXL (thin wall, higher temp): Engine bay, underhood sensors, ignition
• SXL (standard wall, abrasion resistant): Heavy-duty circuits, battery cables, chassis ground
• Benefit: Right wire for each location, no over-engineering or under-specifying.

3. Branch Lengths Customized to Your Vehicle
Off-the-shelf harnesses never fit perfectly - branches are too short or too long. We design to your 3D CAD model or physical sample. Benefit: No excess coiling, no stretched wires, clean installation every time.

4. Color-Coded Circuits and Printed Labels
Each wire is printed with circuit number and function (e.g., "A12 +12V IGN", "C31 GND"). Benefit: Technician can troubleshoot without tracing wires end-to-end - faster repairs, fewer mistakes.

5. Overmolded or Taped Branches
Y-junctions and branch points are either wrapped with high-temp tape (flexible) or overmolded with PVC/TPE (rigid, waterproof). Benefit: Strain relief prevents pull-out at the splice, no exposed wire bundles.

6. Weatherpack or Unsealed - Your Environmental Spec
Choose IP67 sealed connectors for under-hood, exterior, or off-road applications. Choose unsealed connectors for interior cabin, instrument panel, or dry locations. Benefit: Appropriate sealing level for each zone, not over-specified.

• Wire Types: GPT (economy), TXL (thin, flexible), GXL (thin, high-temp), SXL (standard wall)
• Wire Gauge Mix: Different gauges for power, signal, ground in same harness
• Terminal Plating: Tin (economical) or gold (low voltage sensors)
• Sealing: IP67 weatherpack (full seal) or unsealed (interior only)
• Jacketing: Corrugated loom (split or solid), braided sleeve, heat shrink, tape wrap only
• Identification: Hot-stamp wire printing, heat-shrink labels, flag tags, QR codes
• Protection Devices: Inline fuses, fusible links, relays, diodes, resistors
• Branch Overmolding: Rigid (PVC/TPE) or tape wrap (flexible)
• Packaging: Anti-static bag, cardboard box, custom shipping crate

1.Mike R., Automotive Restoration, Ohio
"1970 Chevelle restomod. Needed a new engine harness for LS swap. They built a custom harness with TXL wire and Delphi connectors. Saved $300 vs 'universal' kit that needed hacking. Fits perfect."

2.Jessie L., EV Conversion Shop, California
"Classic Mini converted to electric. 12V auxiliary harness powers lights, wipers, heater fan. Used GXL wire (under-bonnet heat). Deutsch DT connectors. Much cleaner than my hand-built lash-up."

3.Carlos M., Fleet Maintenance, Texas
"20 work trucks, lighting harness failures were constant (PVC insulation cracking). Switched to custom TXL harnesses (thin-wall XLPE). No more shorts from chafed wires. They even printed circuit numbers - my techs love it."

4.Sarah K., Off-Road Builder, Arizona
"Rock crawler buggy. Harness needed to survive desert heat, mud, and vibration. GXL with overmolded branches. Metri-Pack 280 for headlights, DT for ignition. 3 seasons, no electrical gremlins."

5.Dave P., Agricultural Equipment Dealer, Florida
"Sprayer tractor lighting harness - old one was a rat's nest. Sent them a sketch. New harness has correct branch lengths, taped Y-junctions, and weatherproof DT connectors. Plugged right in. No diagram needed."
