I have a 2006 60hp etec with system check. I have an irritating short in the tachometer wire that has system check. If I reach under the console and move the wire bundle attached to the Tachometer so it makes contact , and hold it , it seems fine. If I let go it will connect and disconnect on and off ... My question is is it worth my time to try to repair the deutsch connector / end of wiring harness near the tachgometer or am I better off just putting in a new wiring harness?
The Deutsch connector is pretty easy to repair and all the parts are available at your dealer. Illustrated step by step procedures are in the factory service manual or in online videos.
Inspect everything thoroughly first, it could be as easy as the connector not being fully seated into the back of the gauge.
