I had trouble following exactly what your question about the relays, but you'd do this:
Get TWO automotive SPDT relays and wire like this:
86 on both relays: constant fused power
87 on both relays: ground
87a on both relays: nothing
85 on Relay 1: Lock wire from remote start, AND arm (or "pulse-after-start") wire from remote start
85 on Relay 2: Unlock wire from remote start, AND disarm wire from remote start
30 from both relays: Run these wires together, run them to the arm/disarm wire on the Caravan, but don't add resistors or connect them to anything just yet.
Now, you asked if you need to change the values of the resistors, now that you're using relays, right?
Well, here's what you do.
Take that 30 wire from one of the relays, strip a little off the end, and hold it against a resistor with your finger. Hold the other end of the resistor to the car's arm/disarm wire, and try your remote. See if it works right.
I like to make a habit of trying it both with the car off, and with the car running under remote start. My theory is that the car's voltage is higher when running, and so you want to check it both ways........just an unproven theory but doesn't hurt.
Now grab 30 from the other relay, put your other resistor there by hand, and try that one too.
Once you've made certain that all works correctly, you can now connect and tape up your resistors in a secure, permanent manner.
P.S. Doing it this way, keeping the resistors separate from the relays.......and tying the resistors down low by the Caravan's BCM.......if you ever have to change a resistor value, it's easy. You don't need to touch the relays again, and don't even need to take the dash panel down.

Right now, I have to blu/black wire from the alarm going directly to the WHITE/ DkGreen wire at the BCM plug.
Unless Ive made a mistake,,,here is what I believe I need to do.

Chris suggested that you test the functions before making it permanent. Ultimately, it should look something like this:
