This harness seamlessly connects to the engine bay fusebox and interior body connectors (2\/3, depending on your year\/country\/engine). Most factory functions are retained; details on what stays and what doesn't are further explained below. The harness doesn't include a new battery cable, so you'll need to strip this from your existing wiring (check out the video at the bottom of this page for a guide). However, we're considering offering this in the future.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0907\/7568\/3414\/files\/OPTIMIZE_BACKUP_PRODUCT_Screenshot_2026-02-08_211700.png?v=1771155022\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch3\u003eIs your build ever evolving?

We include 2 breakout connectors for this purpose, one in the engine bay and another in the interior. Because everyone's build is different, we decided the best approach would be a modular harness. This means everyone has the same main harness, which keeps costs low, and people can then choose to have whatever extra features they would like.
