2004 dodge ram 1500 remote start

I have been reading up on all the info I can find here before attempting to install a remote start. I installed a remote start once before on my 97 civic and it wasn't too bad but the 04 Ram seems more complicated. It is a 2004 Ram 1500, V6, Auto, no chip in the key, and no power windows or locks.

I am ordering the Omega mars-33 (any opinions on this system?) and I want to make sure I know what to do so I can begin the install as soon as it arrives.


The problem I have is that according to the vehicle diagram there are 3 ignition wires (pink/white, pink/green, and pink / YELLOW) and 3 accessory wires ( 1 dark blue and 2 pink/white).

The mars-33 has 1 output each for ignition and accessory plus an additional output that can be used for either depending on the position of the jumper.

Do I need to energize all 3 ignition wires and all 3 accessory wires?

If so then I suppose I will need 3 additional relays.

When hooking up the relays I assume 30 would go to constant +12v and 87 would go to the accessory or ignition wire I am trying to energize.

What wires should I use to trigger the relays? Can I use the same wires to trigger all three relays?

Sorry for the long post, any help is appreciated.

i have it as

ign 1 - pink/green (+)

ign 2 - pink/white (+)

Acc 1 - blue (+)

Acc 2- pink / YELLOW (+)

wire it like so for the relays
85 - negative trigger from rs unit (acc or ign)
86 - constant 12v
87 - constant 12v
30 - additional acc or ign wire on car

if you are using the negative output to trigger more than one relay, you should diode isolate them.

Thanks for the quick reply.

When I look at my vehicle's wiring information using the link on this site some posts list an additional ignition and accessory wire but some posts only mention the four wires you have listed.

I also read that I should energize all ignition wires or I run the risk of bad things happening (like check eng. light or not shifting out of 3rd gear).

I guess i will try using the 4 wires you have listed I just want to make sure I don't screw anything up.

The extra trigger wire on the mars-33 is defaulted to use for a 2nd ignition wire so I will leave it that way and use a relay to energize the 2nd accessory wire.

when diode isolating the relay (connected according to the previous post) do I put the diode between 85 and 86 with the white stripe facing the 12v side?

diode inline with 85 or negative trigger.

you will also put a diode across the relay terminals band towards positive side.

Great, thanks for the help.

I was under the dash today with my multi meter finding and labeling the appropriate wires to speed up my install next week and I ran into another issue.

The parking lights coming from the switch are - instead of +.
I also noticed I have a separate fuse for the left and right parking lights.

I was probing some wires under the junction box under the hood and I found at least 3 that showed +12 when parking lights and headlights are switched on so I'm not sure what to do.

Can I run a long wire to the tailgate area and hook right to the parking light assembly?

parking lights (+) - WHITE/ gray @ left of steering harness.
