Hi Guys, I bought a prostart ct-3300 for a 2001 dodge caravan with out OEM keyless entry (with power locks). My question is, how do I hook up the door locks? Do I buy the ProStart Door Lock Kit from Canadian Tire? Do I install two relays or can I hook up the two wires from the prostart direct to the single wire for the door locks?
Also, what is the doorpin for and do I need to hook it up?
Thanks in advance, Mike

This vehicle uses a 1-Wire Door Locking System requiring a (-)Negative thru a 5200 Ohm Resistor for LOCK, and a (-)Negative thru a 2000 Ohm Resistor for UNLOCK. You will need to instal to relays for the doors to work.. The door pin does not need to be connected in your application. https://64.85.6.129/extrainfo/diagrams/29358_CARAVAN_CHRYSLER%20MINI%20VAN%2001%20-%20UP%201%20WIRE%20JBS%20UNITS.pdf refer to this link for the wiring of the 2 relays.. in the pdf file you will notice three different examples.. use only the first one.. -------------

Thanks for the info. I live north of Toronto. Do you know where I can buy the relays and resistors? What values does the relays have to be?

you can pick up the relays at any Canadian Tire. Their part number is 34-0687-6. It is a DLXK-100 rleay kit.. there should be 2 relays and 2 sockets. You will need a 2000 ohm resistor for unlock and a 5200 ohm resistor for lock. Follow the first example on the pdf I sent you and you should have no problems.

The unit being a Prostart, I wouldn't bother with the relays. Just use the resistor inline on the wire. This has always worked for me on Prostart units.
