Dodge ram 2005 Tach wires?

I looked at the post of the wiring diagrams for the truck.  It stated PCM, orange plug, pin 34 driver side.   What it doesn't state is where.    Also said something about  the ignition coil other than the BROWN / white.     Any help would be appreciated.  Almost done this alarm(997 prestige)

when it says ignition coil other than BROWN / white that means you can use the other wire at the ignition coil other than that color. the BROWN / white is the common wire and you can use the other wire on the coil. it should be that difficult to find we did an 03 ram yesterday and had the underhood stuff done in about 30 minutes. good luck and hope this helps. btw, look on your tech sheet it should state somewhere on it where the PCM is located it maybe be in the notes portion. good luck and hope this helps."I cannot teach anybody anything, I can only make them think."

Thanks.....The other wire besides the brown and white worked fine.  Seemed much easier too than going to the PCM.
