Land Rover Defender restomod with LT1 V8 and 10L80 gearbox wiring integration

Restomod wiring / modern powertrain integration

LT1 V8 Defender Restomod Wiring and 10L80 Powertrain Integration

A modern V8 Defender restomod project using an LT1 engine and 10L80 automatic gearbox. VASS supported the wiring for the vehicle and powertrain, including electric windows, central locking, upgraded audio, reversing camera and production-focused scanning work.

Project introduction

The objective

Install a modern LT1 V8 and 10L80 automatic gearbox into a Defender while upgrading the vehicle electrical system to a standard suitable for repeated builds and future production work.

The brief

Support the wiring of the complete vehicle, not just the engine. The work covered the modern powertrain, vehicle harness, comfort features, reversing camera and supporting scan data for components that could be replicated in future builds.

Engineering challenge

Problem, then system response

01 — Challenge
  • Replacing ageing Defender wiring with a cleaner custom harness approach
  • Integrating a modern powertrain into an older vehicle platform
  • Adding modern comfort and electrical features while keeping the system serviceable
  • Supporting repeatable production rather than a one-off wiring job

Engineering & integration

Turning architecture into a vehicle

VASS scope
  • Custom vehicle wiring harness design/support
  • LT1 V8 powertrain wiring integration
  • 10L80 gearbox electrical integration support
  • Electric window wiring
  • Power door lock wiring
  • Upgraded audio system wiring
  • Reversing camera integration
  • Subsystem wiring and testing
  • 3D scanning of mounts and components for future replication

Commissioning & result

Development outcome

Outcome

The vehicle wiring and powertrain systems were brought together so the Defender operated as intended. The scanning work also helped support the creation of repeatable parts for future similar builds.

For similar programmes

This project shows that VASS is not limited to EV conversions. The same structured wiring, diagnostics and systems-integration approach can support high-end restomods, engine swaps and production-style Defender builds.
