2015 Wiring help

Scott91370 · Jan 14, 2023

Tree rat chewed 7 of the wires under the hood of my 2015 Lariat (502a, FX4).
I've fixed a couple of the junctions already but have two wires that I cannot even find corrosponding ends for.

These are the wores that I have 'fixed':
Brake Booster Vac Sensor: Purple/Brown, White/Blue, Yellow/Orange
Brake Res. Fluid Level: Black/Yellow, Lt Blue/Purple

Wires still unhooked:
Purple/Lt Blue
Yellow/Purple

I'm not sure if make these were connected to some of the other wires and a section is missing or what. There were several areas that had a chunk missing so it could have had a connection there.

if anybody has a 2015 they could check under the hood (driver's side) and maybe see where these go I'd be forever greatful!!

Update..

Here is a pic of the wires. All wires went in the direction of the red arrow.

I dont' think the wires I have left over go to any of the others because I foud about 16" of chewed stuff in the fender well area (where the yellow arrow points). Still searching for the other end which more than likely has a plug connector on it.

Did you check the wiring diagram stickies in this sub forum?

I did but didn't see the 2015. Not saying it isn't there, just that I didn't see it. The colors for newer years are different.

You posted while I was answering my own question though.

FOUND IT!!!

Decided to connect the wires that I knew what they were and then start the truck. The CEL came on right away for Intake Temp Sensor error. These wires go to the sensor on the...wait for it... Intake tube!!!
