94 Mitsu 3000GT Keyless Entry

I have no clue if any of what you are asking can be done, but I do know this. You can pick up a keyless entry with two remote for less than $50 and another $50 to have a professional install it. Or $0 when you put a bit of elbow grease and do it yourself. The time it took for me to understand what you are trying to do with the aftermarket/factory function, I think I would have the keyless entry completely install in your vechicle already. No such thing as best system. Price, feature, brand...etc. are all variable. You move one the rest will changes unless you have a constant in between. Below is a wiring diagram to get you start it. Ask ? if you are unsure. Lots of pros. here to help you out.     DIRECTWIRE™ WIRING INFORMATION - MITSUBISHI / 3000 GT / 1994 / Keyless Entry 12volts white    +   ignition harness Starter BLACK / YELLOW    +   ignition harness Ignition BLACK/ white    +   ignition harness Power Lock BROWN / white    -   high on firewall by DKP Power Unlock BROWN / blue    -   high on firewall by DKP Lock Motor blue/black      drivers kick panel Unlock Motor blue/red      drivers kick panel Parking Lights+ GREEN / WHITE      white molex left kick Parking Lights- green or grn/blk      left side of column Hazards           Turn Signal(L)           Turn Signal(R)           Door Trigger RED / GREEN/ sil dots    -   left side of column Dome Supervision           Trunk/Hatch Release           Power Sliding Door           Factory Alarm Arm arms with lock        Factory Alarm Disarm GREEN/ blue    -   ETACS mod. under dash Notes: Must be relay isolated from the door key cylinder The ETACS module is located left of the steering column close to the drivers kick.
