tachometer install
I am installing a tachometer on a 2003 ford f150 4.2L , I am having a little trouble figuring out which wire at the PCM to use. I know on the '98 models it is the white wire with a red stripe, connector 104, pin 48. That wire doesn't exist on this truck, If anyone has done this install let me know how you did it.

Hi and welcome to the forum 
I believe that on your truck you will need an adapter to wire up the tach, such as the one at http://www.egauges.com/pdf/AutoMeter/561.pdf or http://www.exclamationagiftshop.com/...ms_tach_.shtml
