2001 Caravan remote starter problem

hello again, i wanna say thanks to those who gave the advice and info, because today i had another one of those vans and i wired it up according to the sheets and ran a relay with all the resistors needed and other junk like that.

works great even when cold, but only one prob, engine light came on, anyone know why? i ran the relay of the ground when running and the other side the coild to my starter wire, then the diagram said to ground pin 30 and run pin 87a through the reisitor to the violet/brown wire which i did, it also show a diode with the strip towards the remote starter.  other then that all the wires are hooked up normally....guess dodge vans don't like me

I found the "check engine" light came on almost every time I worked on it (generally I had disconnected the battery for safety when I did some of the wire changes, in case of an accident.  I found that it cleared as soon as I disconnected/reconnected it for a few minutes again.  I suspect it's just picking up the fact that someone has cut the power for a time.  It went away every time, and has never come back.

My next project.... I bought a mess of stuff on ebay for about $25 with shipping.... a lot of no use, parts of a Koss CD controller unit, several older Rattler remote starters with some bypasses and quite a mess of relays in rows (the Rattler ones seem to have used whole rows of relays in the past... relays can come in handy) and he threw in a fairly new Rattler 369D starter unit that seems to have everything with it except a remote.  I should be able to pick up one of those at a dealer.  It still had a valid access code for tech info at Directed (Rattler HQ) so I went online and printed off the data sheets for my old '91 Dakota (no multiplex!) and will install in it some time. 

I printed off whatever I found for the '01 and '02 Caravan as well, just to see if there is anything interesting.  Didn't show any difference in the years... I think my Caravan is a "late 2001".  The only difference from the data sheet for the Command Start is that CS says for parking lights a 5.6K resistor, and Rattler says a 2.1K resistor. 

Can anyone clarify from another starter company spec sheet what the resistance to ground should be for parking lights on 2001 Caravan?  5.6K or 2.1K?

5.6k ohm is the right resistance fro the park light on the 2001 caravan ,also it is a neg .
