Like the factory K-series harness it ends at computer plugs A and B, so you need a K-Series Chassis Adapter for your chassis, which also adds the E-plug.\u003c\/p\u003e\u003ch3\u003eHow are the cam sensors wired?\u003c\/h3\u003e\u003cp\u003eRywire wires the TDC plug on the intake side and the CPS plug on the exhaust side: the exhaust cam sensor is the timing reference and the intake sensor references VTC position. The two plugs are identical and sit next to each other, so if you prefer them the other way, swap wires A25 and A26 at the computer plug and reverse the plugs.\u003c\/p\u003e\u003ch3\u003eCan Tuned By Shawn help with the rest of the swap?\u003c\/h3\u003e\u003cp\u003eYes. Email service@tunedbyshawn.com with your engine, chassis and ECU before ordering if you are unsure which configuration you need. If you would rather run a standalone computer, Rywire also builds the K-Series Haltech harness (K2-Haltech-Elite), and Tuned By Shawn can tune your swap on Haltech.\u003c\/p\u003e\u003c!-- why-faq --\u003e\u003ch3\u003eShould I buy the Rywire mil-spec or budget tucked K20 harness?\u003c\/h3\u003e\u003cp\u003eBoth use the same Version 2 layout and connectors.
