tachwire for dodge ram 2007.5 6.7l diesel

Can someone please tell me where I can find the tach wire on a 2007.5 (later 6.7L version that they switched mid year)? If someone could give me a pinout it would be greatly appreciated. Thanks in advance2007.5 6.7L Cummins Diesel

Camshaft position sensor, 3 pin plug, left of ECM, test which lead. One will read 12V+ on ignition, one will go to ground, test the other:- DMM, set to 20V AC. Black to ground red probe to suspect wire, run engine, should get around 3VAC at idle, increasing as you rev up. Or you could use an inductive sensor such as DEI 464.

Thanks ALOT for your help. It is greatly appreciated. Right now I am having trouble finding the parking light wires. Internet says WHITE/ yellow WHITE/ gray in the lower drivers kick panel but those wires are not there. Any insight on where I can find them?2007.5 6.7L Cummins Diesel

Give me 5 minutes, I'll post the installation info on 07 and 08 rams in the Downloads/Manuals section on this site. Isn't the internet wonderful, I'm at least 3000 miles away. How long would this have taken back before the internet.

Go to Downloads/Manuals, enter Dodge RAM, I've posted 2007 and 2008.

Awesome.....thank you so much for your help.    One last question.   This is the diesel verson so I need to wire the wait to start....the PDF you provided says to reference directfax document 1091. Any idea where I can find that? Google wasn't very helpful.   Thanks again for your help2007.5 6.7L Cummins Diesel

Again, just uploaded it as DEI tech tip 1091 in the Downloads/manuals section. Saved me suggesting just that and doing a diagram. I didn't actually look but make the delay 4 seconds, no longer.

You are awesome. Thanks so much for your help!2007.5 6.7L Cummins Diesel

So i am wiring the door trigger wires. Each door is independently wired so I extended the wire to the alarm harness. My alarm (5902 viper) has only one door trigger input, so I used a diode on each of the 4 input wires. The issue I am running into is, all four doors have to be open in order for the trigger wire to notice a change. How can i get around this?2007.5 6.7L Cummins Diesel

Check your wiring and the alarm that shouldn't happen. Make sure all the diodes have their bands away from the alarm and you've wired to the alarm's green not violet.
