I am going to do a remote start for my dad's 02' dodge dakota this weekend. I have the wiring diagrams etc, but my question relates to the remote start install instructions. It says that starter output, accessory, and ignitions (there are 2 ea I believe) must be less than 30A to use the outputs of this device (crimestopper rs800-III) and refers to heavy duty and industrial vehicles. I have done 3 remote starts in the past and have never heard of ignitions/starters higher than 30A (and have done no industrial vehicles). Looking at the fuses in my own 03' dak, some of the ignitions and acc. are fused at 40-50A in the engine bay fuse compartment. There are also factory ignition and accessory relays in the engine bay fuse compartment. Can I safely connect to the ignition harness in this vehicle without the use of high amperage relays? I'm asking ahead because I do not want to get stuck leaving his truck unfinished while I order high current relays.
Thanks
Anyone with more experience have any tips for me? If you have done a dakota or ram, what ampacity does the ignition conductors/devices have to be? Thanks.
I put a remote start in a 2001 Dakota Quad and have had no reported problems and it has been in there for 3 years or so and the unit had built in relays, it works fine.
I am in the process of installing a 791XV in my 04 Dakota Quad Cab and do not plan on using higher amperage relays even though I noticed the same thing about the 40 and 50 amp fuses as you did. If you really want to get technical take a meter and see how many amps it is pulling when running in park.

I'll have to test that tonight with my truck and see what I come up with. I do not know if the wires served by those large fuses are the ones in the ignition switches, I noticed relays beside the fuses (toward the drivers side) in the compartment and I wonder if the control to those relays is what goes through the ignition switch itself in lieu of running the hot/high-current side of the relay through the ign. switch. I'm sure someone on here has an obvious answer to this. Thanks.
I have the service manual on cd for the 2004 and no the ignition leads do NOT drive relays. This is how it goes for the ignition switch.
RED / YELLOW is fused at 20 amps and sends power to YELLOW(START), DARK GREEN/ RED(RUN/START) and DARK BLUE(RUN/START)
PINK/BLACK is fused at 50 amps and sends power to BLACK/ ORANGE(RUN)
RED is fused at 40 amps and sends power to BLACK/ WHITE(RUN/ACC)
RED / LIGHT BLUE is fused at 40 amps and sends power to DARK GREEN (BLOWER MOTOR, i.e. run position)
RED / BLACK is fused at 50 amps and sends power to RED / WHITE (RUN-ACC)
Hope this helps.

Did you get yours going? I finished mine yesterday (791XV with remote start). I have each circuit power by an individual relay (so there are 5, two normal sized ones and the others are in the XCRS). It seems to function as it is supposed to.
