Clicking Noise from under dash

[Tman123]

So my truck has decided to make a clicking noise randomly as I drive down the road or have the key in the 'on' position (whether the engine is running or not). The clicking goes away every time I hit my brakes. I've checked all fuses and all are fine. The noise is coming from the Gray plug that is behind the Black plug that has what I suspect to be the master wiring harness for my whole truck.

No SES or any problems.... so far.... Just an annoying clicking sound whenever I don't have my foot on the brake.

Anyone have any clues as to what it could be/is?

sounds like a relay clickin in and out, which one i'm not sure

I'm thinking its my turn signal relay... it makes the same noise as the turn signal and it doesn't click when I depress the brake pedal or turn on the turn signal. But I'm not 100% on that lol

Try cleaning both ends of the Neg battery cables and........if that doesn't fix it get your batteries load tested. Low voltage/bad grounds can cause all kinds of weird electrical symptoms on these trucks.

Well it seems to have solved itself lol. Just like my head light switch, you use it enough it will fix it self!

Well..... the noise is back.... and is worse then ever now. It happens whether my truck is running or not. Upon further inspection, it sounds like the thing clicking is attached to where the trailer wiring plug is. (its something that is black and has what looks to be several plugs going into it )

Any Idea what it could be?
