I need the diagram of the multifunction connector, the one that goes in the column under the steering wheel, the one that controls the lights?

Sure, here are the wiring diagrams for the blinkers. Check out the images (below). Let us know if you need anything else.

Thank you very much. However, I do have another question: the multi-connector on the column suddenly burned a pink cable that came out of the hot-spot and stopped working. I've been driving without lights for a long time. I don't go out with the truck at night, only during the day, as a precaution.

Good idea, With the key on, I would test the fuse #16 turn back up in the fuse panel under the dash.

Here is a guide to help you:

Let us know how it goes.

I have already checked fuse 16 and everything is perfect without any problem, thank you. If it is not too much trouble, could you help me with the diagram of the connector that is located on the firewall?

I think this is the one you need. Check out the images (below). Let us know how it goes.

Thank you very much for helping me! Thank you very much! Greetings from the state of Morelos, Mexico!!!
