2007 dodge mega cab deisel

i need to know if this truck has the need for a bypass unit and what the wireing schematic is for a auto start     thanks...

Here is the wiring schematic for the 2007 Dodge Diesel. I have installed remote starts of 4 of these 07 Dodges and they are not fun. I use the I Datalink Model ADS-AL CA Multi Bypass Module which will do    the transponder bypass and also the following:

• Door Lock / Door Unlock
• Arm OEM Alarm
• Disarm OEM Alarm
• Panic Mode
• Door Status Output
• Tachometer Output

DEI also make a similar Multi bypass unit which is the DEI Part #: IOM-Chrysler-7. Using one of these modules is the only way to go! Hope this helps.

Schematic for 2007 Dodge PU
12volts      lt. blue/red (2A)       +       ignition harness

Starter      yel/gry (not for remote start)      +       near battery, gray plug
Notes: There is no positive starter wire required for remote start. Just use the negative second starter wire.

Second Starter      PURPLE / brown       -       ignition harness
Notes: The second starter wire is negative trigger thru an 180 ohm resistor. MUST use a relay. Refer to DirectFax document 1084 for wiring information.
Ignition      pink/white       +       ignition harness
Second Ignition      N/A            
Third Ignition      N/A            
Accessory      same as second starter wire            
Notes: The accessory wire is negative trigger thru a 610 ohm resistor. MUST use a relay. Refer to DirectFax document 1084 for wiring information.
Second Accessory      N/A            
Keysense      N/A            
Power Lock      PURPLE / dk. green       -       DKP or cluster, sml gry plug, pin 3
Notes: Lock is negative trigger thru an 820 ohm resistor. Unlock is negative trigger thru a 330 ohm resistor. MUST use relays.
Can also use Directed interface module.
Power Unlock      same as power lock wire            
Parking Lights+      WHITE/ yel (L), WHITE/ gray (R)       +       harness at top of driver fender
Parking Lights-      WHITE/ lt. green       -       sw or cluster, sml gry plug, pin 5
Notes: Parking lights are negative trigger thru a 1130 ohm resistor. MUST use a relay.
Hazards      WHITE/ orange       -       sw or cluster, sml gry plug, pin 8
Notes: Hazards are negative trigger thru a 120 ohm resistor. MUST use a relay.
Turn Signal(L)      wht/lt grn (F), wht/dk grn (R)      +       harness at top of driver fender
Turn Signal(R)      WHITE/ tan (F), WHITE/ yel (R)       +       harness at top of driver fender
Reverse Light      WHITE/ lt. green       +       harness at top of driver fender
Door Trigger      see notes       -       each kick or cluster, lrg gray plug
Notes: The LF door is purple in pin 1. The RF door is PURPLE / white in pin 4. The LR door is PURPLE / orange or PURPLE / gray in pin 2. The RR door is purple / YELLOW or tan / YELLOW in pin 3. Use all four wires and diode isolate each wire from each other and the instrument cluster. See DirectFax document 1076 for wiring information.
Dome Supervision      yellow/lt. blue       +       A pillar or cluster, wht plg, pin 21
Trunk/Hatch Pin      N/A            
Hood Pin      PURPLE / lt. blue       -       hood pin switch
Trunk/Hatch Release      N/A            
Power Sliding Door      N/A            
Factory Alarm Arm      arms on lock with door open            
Factory Alarm Disarm      factory remote only            
Disarm No Unlock      with ignition and Sentry Key            
Tachometer      dk. blue/gray       ac       PCM, BLACK/ orange plug, pin 34
Notes: The PCM is on the passenger side firewall. The BLACK/ orange plug is the second plug down from the top.

On SRT-10 models, the tach wire is in the top black plug, pin 18.

On diesel models, the tach wire is at the ECM on the lower driver side of the engine, front 60 pin plug, pin 24, or at the camshaft position sensor just left of the ECM, in a 3 pin plug.

On gas models, can also go to any ignition coil or fuel injector and use the wire that is NOT BROWN / white.
Wait to start      see DirectFax document 1091            
Notes: On the remote start, make sure to program the Accessory State During Wait To Start to ON.
