Full Custom Engine or Chassis Harness

$2,000.00

This service is for full custom wiring solutions — whether you’re rewiring a racecar from the ground up or replacing a hacked-up factory harness with something that actually makes sense. Every harness is designed around your car, your ECU, and your goals. No universal kits, no shortcuts.

Complete engine or chassis harness — built from scratch

• Custom wiring diagram and pinout documentation

• Proper gauge selection based on device and load

• Fully loomed and labeled (Raychem DR-25, expandable loom, or customer request)

• Terminated with Deutsch, DTM, or MIL-spec connectors as needed

• Relay and fuse integration (or PDM-ready)

• CAN bus architecture design if applicable

• Built for track, rally, hillclimb, or street-legal use

Who It’s For:

  • Engine swaps (K-series, LS, JZ, etc.)

  • Hillclimb, time attack, endurance builds

  • Street cars with standalone ECUs and extensive mods

  • Anyone tired of chasing gremlins in crusty harnesses

Pricing:

  • Starting at $2,000 for basic chassis or engine harness

  • Final cost based on complexity, connector choices, and material grade

  • Estimate includes up to 40 hours of design and build time

  • ECU pinouts and sensor list required to start

Not Included:

  • In-car installation (available locally by request)

  • Tuning services

  • Pre-terminated kits — everything here is custom
