2nd gen Tacoma wire harness issue

So I was just looking under the hood for fun today and it seems I thought it was mice but as I was feeling it the electrical tape seemed melted and was leaving residue on my fingers so maybe it got hot everything seems to be working fine

 

I see some exposed wires with no insulation. Should probably get in there and at least wrap them individually with electrical tape and then bundle it back up

And welcome to TW

 

I see exposed wire fix that asap

 

Pretty sure I see bare wire.
You are going to need to peel back the tap and repair the sheathing.
I’d also secure the harness with a new zip tie.

 

Yeah there appeared of maybe gotten hot but there no heat next to it and it’s just in one spot

 

You should be able to tell more once you open it up.
A damaged wire can create resistance, resistance creates heat.
Open it up and have a look

 

It looks to me like someone made a hole in the firewall and damaged the harness?

 

I was about to tag the wire harness master.

 

Who would that be?

No the hole has been there sence I bought it at 60k they had pods at some point I take really good care of the truck and I’m always checking things and and all I did was check my fluids when I noticed this

 

You pay a lot more attention than me.
I have to admit, i have a habit of NOT looking at things until “I have to”.
So you’re sure there was no damage there before?

 

Yes positive I detail my engine bay once a month

 

I still think it's from whomever made the hole because it's not only the tape and wires that are bad, the cable tie is also broken.

I would cut the tape off and see how damaged the wires actually are. Hopefully you can get buy with just taping them.

Do no use cheap hardware store tape, it will just fall off, especially under the hood.
