This truck was not equipped with key-less entry. I bought one from Amazon LB-405 and I cannot figure out what wires in the door harness to connect the entry system to. I have a partial color code chart but it is not thorough. I took the switch out of the door and it is a reverse polarity type circuit. I cannot figure out which wires to connect the trigger wires from the key-less system to. Is there a link out there where I can find out how to connect it?

Hi and thanks for using 2CarPros.com.

I am not familiar with the aftermarket system you have purchased. Therefore, it is hard to tell exactly how the manufacturer wants it connected for me. If you have a specific questions about the wiring in the door, I can help.

The best I can do is provide you with a wiring schematic of the power windows circuit and the power door lock circuit. Take a look at them and let me know if there is something specific I can help you with.

Here is a link that talks about checking wiring, if needed:

I hope this helps.

Take care,
Joe
