dodge ram 07 mux wiring?

any 07 that i have done so far doesn't have a starter wire, just the PURPLE / brown mux wire and pink/white ignition so the wiring procedure is different that an 06.  Checking to see if your specific truck has the starter wire would be the first step.  If it does, its just like the 06.  What kind of remote starter are you installing?  You will need 1 or 2 relays depending if your brand has an onboard relay.  Here is how i do them with AstroStart and the onboard relay:

Relay 1

• 86:  12V
• 87:  ground through 560 ohm resistor
• 87a:  (-) pulse before through 8.5 kohm resistor
• 85:  (-) Accessory programmable output from RS
• 30:  goes to 87a on the onboard relay on the RS

Onboad Relay

• 30:  to purlple/brown at ignition harness
• 87a:  to 30 at relay mentioned above
• 87:  ground through 180 ohm resistor
• Onboard relay programmed for starter output

Hope this works out for ya.  It has worked well for me so far.  Im sure you can figure it out if you dont have the onboard relay, you would just have to wire up 2 relays. Post up with any questions.

On the #1 relay that staes pulse before thru a 8.5kohm resistor. Use this value ONLY if the factory security disarms by sliding the key into the key cylinder.

If you need to TURN the key to disarm, use 1.470kohms.

That whole setup is ONLY needed if the rig has "door security"

So just to be sure I get you, if I sit in the truck and arm the alarm, and put the key into the tumbler WITHOUT TURNING IT and then open the door, if the alarm does not go off then I use an 8.5K resistor, if I need to turn the key then its1.47K. This is all dependant on the alarm going off when the door opens. Are we talking the ign tumbler or the door cylinder?
