Hi,

I have a 2003 Dodge Ram 2500 and I am installing the 5100rs from Scytek. I can get my lock to work and door triggers no problem, I can not get the unlock to work. Do I need 2 relays for unlock. I really do not understand double pulse. Can this be explained to me. How do I get the nlock to unlock on transmitter.

DODGE, RAM PICKUP, 2003, Power Lock
Lock requires a negative trigger thru a 820 ohm resistor. Unlock requires a negative trigger thru a 330 ohm resistor. MUST use relays.
Can also use Directed 457C or 456L interface modules.

I got that part no problem I have split my power door wire with 820 neg and 330 on unlock and I tested each wire by grounding relay and I would touch the wire on relay one by one to get the lock to work and unlock to work.

Now this is where I am overthinking, how do I configure both wires on each relay to work.

Does the truck have factery "door" security....if so, double pulse. The first pulse disarms your factory security... the second unlocks the doors, if no factory security, single pulse is all thats needed. Use 2 relays, one for lock, and one for unlock. You can put the resistor in line off of pin 30, or 87....matters NOT.

Thank you KarTuneMan,

I wired up the lock on one relay not a problem, it is my unlock I am having trouble with wire hook up, ca you show me a pic, it would help me. This truck does not have a factory alarm, for door locks.

First, IT IS A SINGLE PULSE QUIT WITH THE DOUBLE PULSE CRAP. Second YOU NEED 2 RELAYS. Third wire them exactly like this, 85 -lock/unlock from alarm, 86 Constant 12V, 30 ground, 87 -output to car. Then put the appropriate resistors on the relay on the output to car.

I have literally done a 1000 of these and never once have I had to use a double pulse for unlock.
