    I am looking for some information to complete the installation of tha remote start system on a 2002 F-250 Super-Duty diesel.  I need the Tach wire. I understand that I am looking for a WHITE/ pink wire but can not find the wire anywhere. I also need the color code and location of the of the Glow Plug light or wait to start light onthe dash.

    I am installing an Omega RX-4 system and need these signals to start the truck in the cold weather that requires longer starter times.

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. For wait to start  diesel vehicles the wait to start light is activated by a databus wire from the ECM. To do wait to start use a pulse timer relay and follow DirectFax document 1091
