The existing harness is wired incorrectly for the auxiliary pressure sensor connection on certain C9 and C15 Petroleum Engines. The harness is supposed to supply a 5V auxiliary pressure sensor feed and it's wired for 8V. If this auxiliary pressure sensor connection is being used it will provide a false pressure reading. |
