i bought this unit off ebay .. for my 73 camaro with '79 wire harness. it is called an Executive Keyless Entry and Security 3000 system. The instructions are not that great. I am aware that there are different types of door lock systems, and it does not go into detail as to how to find which one you have and how to hook it up correctly. I guess it assumes you know what you are doing. It also has a starter interrupt, which i probably will not hook up. I just want lock/unlock with park light flast, and the trunk to open with the remote.

I know there are a bunch of wires coming off the door lock switch and i do not want to use the wrong ones. I also know many times you need extra relays to get these things to work.

Any help would be greatly appreciated. I can fax or scan the directions that came with the unit. I bought it in Nov '02 and would like to hook it up one of these days [img]smile.gif[/img]

You can probably get your lock/unlock to work without any additional relayes. My 77 Type LT has a harness connector right above passenger side kick panel that the door lock system runs through. I was able to tap the lock and the unlock circuits here and did not have to remove door panels. You can also get the dome light from here since the door pin is in the same area. Door pin is also neg ground. ! thing: If you do not get a big/long enough pulse from your keyless system alone to operate door locks, you will then need to use relays. Using a multi-meter you can identify lock and unlock by looking for 12 v pulse when you operate the switch. Do this by back-probing wires on connector. I am out of town this week or I would look at the car to identify the colors of the wires for you . I would skip starter interupt. Hope this helps ...

If you are unsure about the wiring, don’t guess at it. Some door lock systems require external relays while others will not. Some door lock wiring does not require cutting the factory wiring and just piggy backs on top of it while others require wires to be cut apart and separated. If the directions are not clear as to what type of outputs are coming out of it for the door locks then you could power the system up and then test out the wires to see if they are a negative output or a positive output. The only thing is you won’t be able to tell how much current they can handle and this is part of the reason for external relays.
Some of the systems out there also have internal jumpers that allow you to change features or polarities to work more with the vehicle it is being installed into.
As far as wiring, make good connections especially for the grounds and power and make sure things are fused properly.
Normally the trunk output wire will require a relay to wire to the trunk solenoid. The starter or ignition interupt relay needs to be of a good quality like a Bosch or Potter Brummfield. The off shore relays with only 4 terminals on them are a lot of times cheap and not real reliable. If you do wire up the starter or ignition interupt try and make it to where you are using the normally closed contacts. When the system is tripped it will open the contacts and not allow the car to start or run but should a failure occur with the system, the main fuse can be removed and allow the car to start. If you use the normally open contacts then a signal has to be sent to the relay to allow the car to start or run.
The parking light wire also needs to be on the parking lights and not the dimmer circuit.
