Built to order with a standard lead time of 4-6 weeks.


We build these harnesses in-house with all the necessary provisions to run any 07K in any chassis. A true plug and play universal and stock chassis standalone ecu solution utilizing the stock dash or an aftermarket dash.


Our harnesses are constructed exclusively of motorsports grade materials. We design these harnesses to route from below the intake manifold, making it super discreet and tucked. We then use a subharness based construction to keep the motor super serviceable and allow for future expansion. For instance, all the useable outputs and inputs are pre-pinned to these subharness disconnects so adding in additional sensors and features down the road is easy. We like to call this future-proofing.


Our standard harness length places the ecu 4-6FT from the oil fill cap. This lets you mount the ecu where you please and allows these to be fitted in any chassis. We also include a configured basemap with each harness and our end user support is unmatched. When you’re ready for your first start let us know and we’ll hop on a TeamViewer call and get it idling for you; this typically takes 5-15 minutes.
