Any ideas....wiring issues

Just wondering if anyone knows what this could be. Thinking it was wired to an amp. The brown wire with circle connector is tied into that independant fuse

It was shoved into an empty fuse, unhooked it and everything still works sooooooo......

Also does anyone know what color the wires are supposed to be for my 6x9`s in my doors. They are gone and so are the wires. I have a aftermarket deck hooked up and am kinda curious where the power is going since its tied into whatever wires are supposed run to the rear of the doors

Lastly trying to get my power door locks to work but some ahole actually cut the rod, I replaced the breaker and the pwr motor is just buzzing, does this mean it works. It`s riveted in so if its working I dont want to cut it out.
Its a 91 F150 xlt lariat

That connector is typical of a ground terminal. Black with a white trace is front door speaker negative on both doors, white with a light green is right side positive and orange with a light green tracer is left side positive.

But a ground terminal for what? And I doubt it should just be shoved into the fuse box like that. I want to trace it and see where it goes, but as you know its winter here in Canada and I dont have a garage
As for those wires, those are currently powering my front door speakers, there are also supposed to be rear door speakers, its a regular cab.

I pulled the pass door panel off and the pwr lock acc. is gone. So I guess I'll have to hunt one down


My question is this. I'm not sure my model came with the speakers in the rear of the doors, though it is set up for it. If it was what color should the wires be, my hanes manual doesnt show the wiring for the stereo.
If lets say there were never speakers there, how can I get power to after market speakers from the deck?

I'm not good with electrical but was thinking
if I disconnect the dead/useless speaker wires running from the deck harness to the factory harness I bought couldnt I run around the factory with my own wires?
Not sure if that makes sense?

the wires probably lead to a harness taped up to a piece of metal in the back. near the factory location. usually they wire it for the speakers.

you can run your own speaker wires though. just make sure you do disconnect them from the factory wiring harness.

I've got left rear negative as dark blue with an orange tracer, otherwise the website would be correct.

So now I am pretty sure this truck was never wired for speakers in the rear doors, see the pic below. Where my speaker wires run from the deck into the factory harness there is in fact only 4 wires. Weird!!!!

Anyway so since there is a space for 6x9's in the door, and I have an set just laying around I figure I might as well toss them in.
So where the speaker wires come out of the deck that aren't being used, can just be extended and speakers hooked into them right? Just pull them apart cut the bare wire on the harness off and I'm good to go?


I wouldnt imagine anyone has any idea which wires arent being used? Can I look in the manual for the head unit, and go from there? I dont have the digram for the in between harness.

So I checked out the manual for the deck and got my speaker info from there duh....lol.
But is the deck power itself or is there a factory amp a 91 F150, I know there was one in my old sunbird.

I would suggest giving your amp an independant power supply as they can draw considerable current. Your deck may have a signal wire that can signal your amp to actually power up, but I don't know if automotive audio components are caught up that far yet from a technological point of view.
