2001 dodge ram--help---

Hi, i have read a lot of the postings here and some are different than others...a couple of questions...

i see the diagram for a 2002 but not for a 2001...are they the same? if not does anyone have one for the 2001 ram?

also, do i have to use resistors and diodes for door locks or parking or dome lights?

can i catch the door lock wires on the drivers side or do i also have to go to passenger side?

what is the best tach source for remote start and where to catch it?

thanks for any replies, much appreciated

Notes:
*1 Keyless models use positive trigger for lock, and 5-wire for unlock. Can also find wires at the central timer module to the right side of the steering column, lock is ORANGE / green, unlock is pink/green.  *2 To avoid dome delay, use tan for the drivers door and BLACK/ lt. blue for the passenger door. Both wires are located at the central timer module to the right side of the steering column. Use both wires and diode isolate each.  *3 Arm is negative trigger thru a 644 ohm resistor. Disarm is negative trigger through a 1.5K (1500) ohm resistor. MUST use relays.  *4 Diesel tach wire is gray/black and diesel wait to start wire is ORANGE / black (-) 'see direct fax document #1090'. Both wires are located on the center of the firewall. There are two black plugs, the wires are in the top plug without the white insert. The tach wire can also be found at the ECM on the passenger side firewall in connector C-1, pin 8. If using the org/blk for wait to start causes a shifting or cruise control problem then use a pulse timer relay instead, refer to directfax #1091 for wiring information.  *5 This wire requires a high current negative, must use relay.
