How rare is a manual IS300 now a days? I have one. 02. Very similar to yours as it has the L-Tuned sides. Your's way lower than mine tho. Mines completely stock except for Ltuned exhaust as far as powertrain goes.

"so many things can go wrong with a solder". Yep and so many things go wrong with a crimp, ESPECIALLY when subjected to moisture. I have repaired so many failed factory crimps by soldering the wire back onto the lug. Yes, enough heat is cruicial, but if you have the fundamental skills, rosin core solder will last forever even in the moist.

I have to strongly disagree. Admittedly it's been at least twenty five years since I did any significant electrical work on cars, but one thing I can easily remember and say is that a good portion of the faults I fixed were due to crimped joints overheating. Typically it is the crimp connections that subjected to water that seem to fail. Covering in heat shrink can help but not always. In fact in some cases it can make it worse as while the tube will prevent water ingress from the wire side it does nothing to stop water entering from the connector side and ends up worsening the situation by preventing the water from drying out. I always replaced the failed crimped joints with soldered ones and even did a lot of modifications, accessories and such always using soldering. Not once did I ever have a soldered joint fail in any way. I do occasionally fix an electrical appliance these days and just a few months ago I repaired my dishwasher which wasn't heating the water. The fault was a crimped spade connector which was overheating due to the bad crimp connection to the point that it melted the solder on the PCB. Needless to say I replaced it and the couple of dozen others with soldered connectors. Maybe your message should be a little different and say "Why you should never solder wires on your car if you do not know how to solder." Also, as you yourself mentioned it is just as easy to make bad crimp connections by using bad crimping tools and bad crimp connectors. If one doesn't know what he's doing I would say it is about as likely to make a bad crimp joint as it is to make a bad solder joint.

Can you show us how you take out the hood step for step please?

Bro used girl math for the bumper and hood 😂

Putting in work! Loving it!

Please stop fucking posting selfie "what's going on guys" videos. jesus fucking christmas

To save you some time, you dont need to remove the radiator. Remove the upper radiator hose, unbolt the fan shrowd and lift it up. That should let you lift it enough to give you enough room for a puller etc.

I’m a marine biologist and will continue to solder all my wires

Game changer

Was going to say this guy doesn't cuss in his videos anymore. But then 2JZ no shit was said! Redeemed yourself a viewer. 🤣

Nice demonstration. Thanks.

Naw, I’ll pass on this channel. But you do have a lot of opinions.

Yep, the waterproof connector looks better. But in a car? It won’t work any better.

I agree with what you’re saying. However, that ‘little bit of flexing’ that you generated on that wire isn’t something that you were going to see happening all that much. How would that possibly take place? Again, I agree with you, that can be a problem. Emphasis on ’can’. But even that ‘twisting only’ connection will work in some applications. Of course I would highly recommend against such. But it could last in some applications.

You need gloves on to solder like a fish needs a fucking bicycle.

been watchin off and on for about a year now your the reason i know my is300 inside and out 🔥🔥💯💯

Better than new

True open barrel crimping is the best

Thank you for putting this information out there. I am getting my first soldering iron tomorrow. Well this morning should be coming between seven and 11 and I’m about to fix what I bought to a mechanic to fix and all he did was twist the wires and wrap them with electric tape and then put it back inside my electric bike. I bought my electric bike home and I opened it and looked at it first I unplugged the main power supply then I looked at it terrible this is not a safe and secure connection for anybody and for any mechanics out there doing this your garbage I’ve called the electrical bike shop garbage to their face. They want to give me my money back. I told them keep it. They needed it more than I did because somebody that they fix. They’re gonna catch on fire. It’s only a matter of time he’s doing it to all of the electric bikes that need fixing no soldering no heat shrinks no nothing just spliced. The wires twisted them up he wrapped the extra wires around the other wire and then wraps it with electric tape and this is a main source that supposed to charge my battery? This has to be a secure connection there has to be wonderful current going on and because I have this knowledge because my father told me this long time ago except my file told me a different theory my pops used to twist the wires and then put a cap on it twist the cap on it and then put electric tape, but I didn’t see that and I wouldn’t trust that anyway on a moving vehicle. Well, it’s electric bicycle but still moves it moves so it has to be secure any loose wires or short circuit these people don’t care about my life or other people’s lives this is a serious situation. Thank you for your advice. Thank you for calling the other mechanics garbage because they are if they’re doing stuff like that just wrapping wires and putting tape around it they’re garbage great content.

Solder joints are zero ohm resistance, our computers rely on low voltage signals to monitor sensors. learn to solder, being inept is not an excuse.

That trash can lid option had me dying 🤣 always resourceful Irvin!

Love my is 300 260k miles just got a Manuel Swap for it 😃

Dope first episode! just nuts and bolts 💪

super excited to see what you have in store....been having some irvin300 content withdrawals...lol

Silver is boutta get some boost?

we have a 2001 IS300 and your videos have been so helpful. the more i work on this car the more i understand the need to get a "daily for your daily" lol

Let’s go. New build. Can’t wait to see what you have in store, I’m going to be here for all of it

Can’t wait to see the build come together!

Must be just me. As all my solder joints on my vehicle wiring i have done are still strong and have never ever had a fire 👍

click bait? dont watch, just solder unledd high vibration

Proper materials, and methods, I will take a western union splice, properly soldered, and in adhesive heat shrink over any crimp. If you are getting solder sweating into the insulation, you are applying too much solder. It doesn't need to be gobbed on like that. Crimps corrode, get hot, get loose, eventually arc, get even hotter, and looser then fail, not to mention they can be a source of RFI, and in a dangerous environment, have to be considered a source of explosion/ignition.

Guys, am I a lazy is300 owner 😂 I decided to buy orange LEDs for the under carriage and painted my calipers orange to match the lighting lol

chill out why you so aggressive my brother

As a guy who does flight cables professionally, i approve this message lol The only thing I would add at the end of the pull strength test part would just be a statement about how the crimp is able maintain flexibility vs the solder joint. Flexibility is key. That's why the wires in harnesses are twisted and etc Thanks for sharing that crimper tool ID i might actually get that for home use. You seem like you'd be good at building racing drones

Only time you have to solder is if your connector just has pins. Like a serial port. Butt splice and heat shrink connects everything on our Shipping container reefer units at Carrier, they are raw steel butt splices though and we heat shrink (with adhesive) after... Or you use specific connectors, with crimped on pins. Good Video...

You will not see either crimp once you put the heat shrink insulation on the end.

In a high flex application such as motorcycle hanlebar switch to chassis . I would choose solder everytime.

Looks great🔥 Is this gloss black or matte black color?

Sure, hack technicians can, and probably will, screw up a solder connection. Those same hacks can, and probably will, equally screw up a crimp connection. By the way, you called that joint with the solder wicked up the wire a "good connection". I disagree... if you wick the solder that far up the wire, you've used too much solder. In 55 years of being a tech, I have never had a solder connection fail, or the wires break at the solder connection. I don't use as many crimp-on connectors, but I've not had any of them fail either. As long as either is done correctly, they are equally reliable. When wires break at the solder connection, it typically is because the wire was improperly stripped of the insulation, and the wires have been nicked. .

I mean… if you can successfully make a clean solder on an automotive application… there’s a good chance you shouldn’t be working on anything electrical to begin with.

Good info, but the weight test at the end is irrelevant without doing the same thing for all the connections.

Your soldering opinion is not warranted. Maybe your soldering technique is lacking.

I was trained by the Navy in HRHS and when you showed that your solder wicked under the insulation, you are showing A failure in your soldering technique. That would not be allowed on Naval platforms! Solder always beats crimping hands down. Never use a crimp joint in your wiring. Crimping always, always causes the wire to deform. Deformed strands are weakened strands and will fail sooner than later. The only exception to that is crimped pins in a plug and those pins do not deform wires as much as crimps and the wires in a plug are held firm behind the plug. Nothing shakes more than a submarine underway and none of my solder joints ever fail.

Scotch locks are the only way to go for any type of electrical repair. By far and away the fastest, most reliable, and effective way to fuck up anything they come in contact with. And wire nuts are for houses. It's amazing the number of those that I have thrown in the trash. Electricians should not work on their own vehicles! Ever!

Irvin, thanks for showing the open barrel crimp process. It's amazing how many other videos that KZbin search algorithm bring up gloss right over it I'm currently using cheap Amazon ratchet crimpers and dodgy Amazon connectors. I think it's time to stump up some cash for better quality I agree that crimping is the way to go for automotive use, especially when you can use oem style connectors

master electrician 25 years you are dead wrong!
