Replacing Stereo wiring harness

I am sure this has been asked before, but my feeble searching skills yielded mainly posts about getting the incorrect subject.

Is it possible to get the (female) pins that slide inside a wiring harness (stereo)? If so, what would I call them, and where would I get them? (Pics below)

Previous owner hacked of the toyota stereo harness and crimped directly to the new headunit. I want to undo this and go back to the factory harness with the metra adapter. I got one of a wiring harness off a parts truck and I was hoping to get new crimp-on pins that can crimp onto the wires in my truck and slip into the wiring harness. Seems it might be easier than soldering the new harness to the old wires.

 

Not sure if something like this would work?

or try Metra, they usually sell the plugs for factory radios

Metra makes the harness, you will just have to connect the wires back on.

From experience, getting the

metra 71-1761 and crimping/soldering it onto factory will be the easiest option

 

I second this.

I've worked on some jungle messes before and definitely the best way to clean it up.

 

Or take it by your local best buy and have their Geek Squad installer do it for you. I'd charge about $25 in my bay for that. Your local results may vary

 

I found it on eBay.... I think it's what you're looking for. It was sold as a complete set to "add rca plugs" to factory radios. Only$15 so you could just throw out what you don't need. I bought one for my 2012 so that I didn't have to cut factory wires.

Don't know if it's still available though. Good luck
