I have a 1995 dodge 1500 ext.cab. I installed a ct 3300 remote start with a neg. door lock out put and I am not sure of what wirs or how to hook up door locks. All help would be appreciated. Thank You
Hi, the locks in that truck are a 5-wire reverse polarity which requires the use of 2 relays. These wires are pink/violet(unlock), ORANGE / violet(lock) and can be found in the drivers kick, or pass. kick. The diagram to wire these relays up are usually included with the alarm install guide. Or follow this:
Locate the 2 Lock wires, cut them in half. One side of the wire is your motor side , and the other side is the switch side.
85&87- 12 volts constant (fused!)
86- lock output from alarm.
30- Lock side of the cut wire
87a- switch side of the cut wire
****If you blow the fuse on your relays, reverse the wires on 30 and 87a****
Good luck, hope this helps.
I have a 95 dodge ram with power door locks. They are 5 wire locks and the auto start remote has a neg. wire for lock and unlock. How do I hook the wires up so I dont blow fuses. Thanks

youll have to use two relays, or get a dei 451m.

youll have a switch side that will show 12 volts all the time, and a motor side that will show nothing. you can go to directed.com and get the manual for the 451m and follor that too.
I have a 95 dodge ram pick up with factory locks. And I have a remote starter with { - } output for lock and unlock. Do i need relays and if so how do I hook the up. Thanks

Use the following for your lock hookup. You will need relays.

instead of building your own harnesses, you can get pre-wired dual relay sockets (p/n DLS for me) that will do a host of doorlock systems, depending on application. Makes 5 wire locks like you have MUCH quicker to do, as ALL of the pin connections are done for you already. And its only a few cents more than a pair of single relay harnesses....

OK, go to a local alarm, retailer and get a DEI 451M and yes you do have to buy this and it does not come with the alarm. This unit retail for around $20-$30 and make 5-wire door lock very simple.
