6 Cylinder Engine
For H6 or 6 cylinder builds like the EZ30D or EZ30R we use a standalone ECU like a Haltech Elite 2500 and build the engine to ECU section from scratch. We then merge this new harness into your chassis harness (part 1). This means we do not need any wiring harnesses from your 6 cylinder car. You can learn more about 6 cylinder swaps here.
Turbo Chassis (ex: 2002 WRX)
We'll need the bulkhead and front harness.
Non Turbo Chassis (ex: 2000 RS)
We'll need only the bulkhead harness.
