Hello,

I have a black box under my dash which has a cable not connected to it. I know it is something to do with the Alarm (or is the Alarm ECU). But I cannot find this particular part online, nor can I find any model numbers on the actual box (or in it, I removed the screws). On one side the cable is not connected, if I connect it all the lights flash and the engine becomes immobilized. My remote keyfob works fine for lock/unlock, so i'm not sure what is going on. It has three other cables going into the other side. The only markings on the box say JT3KD1786-R. I attach pictures. I want to know if this is a standard stock part, can I replace it for another one that works properly? can I reset it?

Any help appreciated!

It looks to me like you're working on the drivers side (based on the brake pedal in the picture). I would have to guess this is an aftermarker alarm. Your key fob is working off the stock keyless entry system which I believe is in the dash behind the glove box. I'm pretty sure you're dealing with an aftermarket unit here.

 

Any idea how I might identify the manufacturer? that might allow me to get a manual and perform a reset / purchase the correct fob. The only code I can find is the one I posted previously.

 

If the name of the company is not on the alarm it's probably a cheap off brand. You might be better of to just buy a whole new unit.

 

Thanks 97DISCOIDAHO.

Any idea is that wiring is standard? i.e. getting another unit would be plug and play.

Thanks

I highly doubt it. It will probably need to be rewired. Good news is... you can find the wires pretty easy now that you have a harness already installed to show you the way.
