Wiring connector for? What do the wires do that run through it? It Is between the computer and inner fender attached to the firewall, thank you.

 

In not knowing what you are specifically refering to, the PCM connectors (there are 3) connect it to various points of the engine and drivetrain components/sensors in order to obtain readings and imput to adjust the engines "mapping" of fuel to air ratio, timing, and other engine requirements.

 

I get that, I forgot to take a pic this morning, but if you looking at the pcm, its to the left of it, clipped into the plastic under the cowl, that houses a wire harness that goes across the firewall. Its a tan connector with maybe 6-7 wires.

 

This isn't my truck, but the plug is shown in this pic, looks tan, above where that blue wire is in the pic.....
