2000 caravan

i just had a problem with a 99 plymonth voyager, i used the white and green wire, it ask for a 1500 ohm on the lock side and a 250 ohm on the unlock side. (one wire controls the locks). when i hooked it up this way, nothing happened, it would lock the doors when i was unarming the alarm, quick fix,   tap the white and green wire, put the 250 ohm(1/2 watt 5%) in place, then diode the green wire from the blue, attach both wires to the Resistor door locks will work the way they should. your white and green wire are under the fuse box, the left plug. take the cap off the plug, cut the tape back.

you don't need a diode,     you do have to use relays and the state resistor values will work fine.   I do these vans very often

Using rlays can you tap to the same white green wire or do you have to find one for lock and one for unlock.murraywatchel
