  1. On the Rywire engine harness, there is a connector labeled H20. This normally connects to the gauge cluster temp sensor located on the upper water neck on the Honda K20. The Hybrid Racing conversion harness has a wire labeled "coolant temp." In order to control the gauge cluster in the EG/DC/EK chassis, you'll need to connect the wire labeled "coolant temp" to pin 6 on the Rywire engine harness.

    93 civic, I have the coolant temp sensor connected to the red and pink wire can I bypass that and just plug it up to the 6pin on the c101

  2. The Rywire engine harness has an "Extra" wire included in the harness. This can be used to control or display an additional external sensor, such as a boost controller, air pressure sensor, etc.

    • There are two wires on the engine harness, they correspond with the C101 connector, pins 11 & 12.

    • Be sure to check the continuity between each wire to confirm the pin locations as they are not labeled.

I didn't see the ALDL connector (data link connector).

Todd, the data link connector is located on our conversion wiring harness and is not part of the engine wiring loom.
