I am installing a remote starter in my new truck. This is Ford's new 6.0 Liter Diesel, I have downloaded the color codes from techweb/wiremagic, they are not accurate. The big trouble we are having is finding a tach sensor wire. We pulled the air filter and looked beneath it and found nothing. Any help would be appreciated, also any problem with door locks? This is a 4 door crew cab with keyless entry.

Thanks

Michael

Is this what you have for info?:

On diesel vehicles the tach wire is green or white, in a 42 pin plug under the clamp on the engine side of the air intake duct.

This is all I have for that.

As for the door locks this is what I show:

With keyless entry use WHITE/ red for lock and BLACK/ white for unlock. They are negative trigger and found at the VSM. On the vehicles with keyless entry the GEM shuts down after the doors have been locked for a certain time period, you need to wake up the GEM for the doors to unlock.

Email me if you want the diagram on how to 'wake-up' the system.

Easier place to find tach.................. on the left side of the steering column, there is a big bundle of wires. Taped to the OUTSIDE of this bundle is four wires that stubb out, taped at the end from the factory. Use the GRN/WHT wire for tach. I did an 03 a few weeks ago, works perfect, and in an easy place to get to.
