Just bought a keyless entry kit for my wifes van. Its a 2003 Dodge Grand Caravan Sport. I noticed there is only one wire operating the power locks (lock and unlock). How do I go about hooking the keyless entry for her van? Any help please.

you could use two 1 amp diodes ,connect each diode to your keyless lock wires with the silver stripe facing the keyless unit. the add a 5000ohm resistor to the lock one and a 1700 to the unlock. connect the other end of resistor together and attach to your door lock wire. this should to it.....but depending on your unit a bit of fine tuning with a slightly higher or lower resistor may be required.

Goto the left bar on this site under BASICS and click RELAYS, then click Single wire systems, then 2000 - 05 Caravan and this will show you the diode method. I actually had a problem with using just diodes on two Caravans where the keyless worked for a day and quit. Thought the outputs would be burned out, but wired up relays and they worked great. The relay setup isn't under relays, so pm if you want instructions.
