Hey Cody, Official NASA Certified Soldering Expert (NCSE) here. Your soldering looks great. So long as the solder flows smoothly through all joints, it's great. You can see when it's finished when the entire solder is smooth liquid.

Cody I work as a part time instructor and I am a service manager at a truck dealership I find no problem with your technique but might I make some suggestions 1 if you use a pin removal tools to remove the pin from the connector so you could slide you shrink tube 2 if you cut the wire use a non insulated barrel connector that you can crimp and solder and the use your shrink tube always use shrink tube with glue so it seals your connection this is the suggested method that I teach in my electrical classes I teach keep up the good video very good content

[MichaelMantion]

EXCELLENT video. It was short, fast pace, no music, great audio, and had unique information. EASILY the best video you have made thus far.

When faced with a large connector like that, you can normally release the pin in it. They normally have a one way barb on them and by getting a very small screwdriver or piece of wire, you can push down the barb to release it to get suitable heat shrink tubing over the connection. But nothing wrong with what you've done or the soldering! :D

I've been using those fuse taps for YEARS. They are reversible, easy to use and work great. They only two problems are how much space they take up and finding always on circuits. Because they overlap neighboring fuses, you can only use them about every 4 fuses. If you need it to be powered when the key is removed, the only real option is to tap the door locks or security system fuse. If you need it on while turning no further than the accessories position, then you also have everything associated with the radio and maybe a 12V outlet. Putting those taps on anything else, you will want to add a switch and make sure you have that switch open while starting your vehicle, otherwise the spike from the starter kicking off could fry whatever is attached to it, particularly LED control boxes.

If you are going to solder the splice you might as well cut the wire and that way you can use waterproof heat shrink but there is nothing wrong with your soldering.

After being in the racecar industry I learned early on you can never solder connections that will be subject to any vibration. They will break and fairly quickly because they are too brittle. So we used aircraft quality crimp terminals after that happened a couple times and never had an issue again. It really sucked to be knocked out of a race because of something you thought was the best kind of splice.

Once you try the liquid electric tape. You’ll never go back. Works great!!

Many moons ago I spent a bunch of years installing mobile electronics (car alarms, stereos, etc.). We used to work on a lot of brand new vehicles, this method was always the preferred method if we couldn't get a wiring kit to tie into the factory wires. We always soldered and taped our connections, never crimp connectors and we always guaranteed our work for the life of the vehicle. The equipment might fail but the installs never did. With practice you can solder and tape as fast (or faster) as any crimp connector. BTW I believe the connector you referenced were 3M ScothLoks

I have a friend that worked in the rv business for a long time and he used dozens of those quick splices a day for 15 years and never had anything come back with a problem. I doubted him a little at first but he told me the only time they are a problem is when someone doesn’t know how to use them and so for he’s been right. Iv us quite a few of them on projects over the years and have had any problems yet.

Speaking as the current top NASA soldering expert...

...looks good.

[martinw]

I like the searchability idea.
I admit I've had this problem finding your old videos.
One nice thing about instructionals is they're less likely to get "hidden" (I'm looking at you, YouTube Algorithm).

[despain]

This was VERY helpful. I have a lot of stuff down, but wiring and electricity...not so much. I've been shocked more than once. Thank you.

[tommycapps]

I really appreciate you taking the time to go over splicing electrical wires. Thank You!

[tonkacaptain]

So happy you will be making the titles and or description less ambiguous in reference to the video's content. Thumbs up on the video and hopefully the change. Looking forward to more "How To Videos"

I'm not NASA certified, but I am PACE certified. I think you did a nice job. If your up for some suggestions. You could have removed the connector from the connector block and then slipped the shrink tubing on and then pushed the pin back in. You typically just need something like a paper clip to remove the pin from the block. Another option is to cut the wire and then used a number of splice joints to get it all back together. My favorite splice is the "Western Union", super strong and very reliable. You would've ended up with a shorter red wire so I understand why you did what you did. I would've removed the connector pin from the connector block to slip the shrink tubing onto the wire. Again, what you did was fine though you would not have passed the certification testing. LOL :)

Did I see a jump cut? Lol awesome video

[MJPeddler]

I enjoy your “How-to” vids. That fuse/splice tap is pretty cool!

[clintonminer]

Another amazing teaching moment. I have a trailer to require and would have done it half way. Now I know better. Thanks

The silicone is a good idea. I usually use Dielectric grease that I get on connections but I need though about using it on soldered connections.

Myself I am fickle about the way my connections look. I would cut the wire and twist in a way so it's straight and use shrink tubing.

But soldered connections are best the plastic wire splices are junk and should only be used in an emergency.
