The Rywire Replacement Engine Harness uses Mil-Spec components for extreme long term reliability over the stock harness. It's designed like a race-harness with individualized sensor wiring like a tuck-harness. An added pigtail at the ECU carries your interior functions to a shock tower connector making the whole harness nearly plug and play. There are just a few wires to connect at the old unused ECU plugs. (For EK Civic customers, it's completely plug and play)

- All harnesses are made with the Electronic VSS plug, you're welcome to ignore this and install your cable VSS if you have a cable driven speedometer.
- The reverse switch plug on the transmission is also always the OBD1 type since this is more common.

	As you can see, the harness is sleeved with a light gray heat resistant tubing. The similar color to the engine itself helps the harness remain stealthy and the individually run injector leads mean you can hide those wire leads extremely well.
	We use factory colored wire to ensure easy troubleshooting years down the line - this harness won’t scare your local mechanic one bit. Follow an OBD1 Service manual and everything will make perfect sense.
	The plug and play pigtail: This carries almost all your interior functions from engine harness to interior harness without splicing a thing.
	Check out how clean the single sensor leads look! When the injector rail is installed, those clips and wires will be nearly invisible on top of the intake manifold.
	The Labels Option: ($100) Add these uber-clean sensor labels and never be confused which plug goes where again!
	The Mil-Spec Firewall quick disconnect plug: ($250) The quick disconnect is useful to have and when a hole is drilled for a perfect installation like Ryans, no engine bay is cleaner.
	The Raychem DR-25 Sleeving option: ($200) Raychem DR-25 Heat Shrinkable Tubing is specially formulated for optimum high temperature fluid and heat resistance. It is resistant to aviation and diesel fuel, hydraulic and lubricating fluids. It's flame retardant with a 2:1 shrink ratio.
