how to bypass mazda's door lock module?

Here is the situation. I'm working with a 2000 mazda MPV and would like to bypass the entire door lock module Problem: The door lock switches (at the doors) close to ground one way and to ground thru a 2.4 k resistor the other, (for lock and unlock) What could be built that will separate between the 2 signals and will allow the use of a standard 3 relay system?

Locate the module and you find the common motor wires, remove them and wire them with your relays or five wire them so that the original switches work, one question, why?commit your way to jehovah and he will act in your behalf. psalms 37:5

x 2 With T&T, incidentally with a 2 wire lock system you will still need 2 relays. Most two wires don't put out enough current to overcome the resistor.

That's how its hooked right now to an aftermarket alarm, problem is...the original lock-unlock switches don't work, (the factory lock module is MIA) I'm looking for a way to incorporate the original lock switches into the system without using the factory lock module.

You have to find the factory wiring diagram. Or first make the switches work. Did they work before the alarm was installed?

How do you mean MIA? Not there or not working. If the second, start checking your fuses.

MIA as in missing in action, I'm guessing it went bad (in the past) and was replaced with an after market alarm/keyless entry, problem is due to the way the one wire switches work, they are not compatible with a standard system (not without the factory module anyway) I'm trying to find a way to make them work.

How many wires coming off of each switch?

2 wires, 1 goes to ground, the other is the sensor wire, the lock position grounds the wire, the unlock position grounds the wire via a 2.4K resistor.
