Yup!



I tracked down the OEM male and female fittings for each end, such that it then becomes a plug and play deal. Wiring enclosed in that hot-rodder sort of heat jacket, often used by that crowd for fuel or brake lines located close to headers.

If any interest, I can post the Bosch male and female fitting part numbers that you will need to use.
