How to connect two pieces of 4awg gauge wire. 

Now I know why I have so many electrical issues with my Ford F250

I love the way you showed absolutely the best way possible to join two stranded wires with the "two wire mesh" method and then walked away as if to say, "look closely and let that soak in for a while". Of course, wrapping with a single strand of wire is a must to keep the projecting ends held tight for the soldering. In my opinion, this is the very best way to solder stranded wire together. Very nice video! Thank you for your substantiation of making the method I've been using, the right way. Have you ever tried to pull the two wires apart after you mesh them, but before you solder them? It's like when you mesh two phone books together the same way. You can't pull them apart with two trucks! (On MythBusters)

I see a lot of guys in the comments saying "don't do it like this"-" trash" -"Mexican job"-"I wouldn't do it that way"-ect.... But don't elaborate on how they would do it?

I wouldn't do things this way but it is a solid connection! If I were to do it this way, I would add rubber tape, then friction before the electrical tape.

Just solder 2 ring terminals on both wires and then bolt them together

Thanks man! I sat there with my soldering iron for 5 mins before I found this video. Great idea with the micro torch.

Cool. But proper heat shrink would’ve been better to insulate. I’m definitely going to borrow the method of using a small gauge binder though.

Bet he charged that customer over $200 in labor

Aftermarket cable ends were installed on my Excursion before I bought it. Eventually, lead to very poor electrical connection to the battery. Ford no longer makes the positive battery harness and this technique is the only way to add new cable ends. It's not pretty, but if properly insulated it will get the job done.

No... With a 3/8" studded insulated terminal block...

Brutal but effective...nice

4 gauge butt connectors are like 1$ a piece or get a distribution block.

Wow, that is the fastest pair of hands I have ever seen/!!!!

Wow, What a Lousy Job. . . ! Done this before on a car, I know it’s much more difficult than it looks. Still, The connection was not wicked completely.

Thats a solid connection. good job.

very helpful thank you

What kind of solder and are you using flux? Thanks

Im glad I've never bought a ford....or had a Ford mechanic

When ur soldering iron fail use a torch

It is nice to see someone use a small butane torch for more conentrated heat rather than a regular torch but damn that is one ugly and unreliable joint.

Mickey mouse job.

You got to be kidding.

Only do this if you absolutely have to.

Where is this splice going.....Nowhere! Thank God for choices.

You didn't use any flux

Dont do like this

Obviously not the right way to do it. Can anyone link to a video that shows the proper way to splice heavy gauge wire?

No.

what a butcher

lol

Wtf is this.
