O2 sensor extension cable

[loki]

you must use crap solder and poor soldering joints, because I extended an OEM shielded MAF wire for a 240SX engine swap, using a donor piece of OEM MAF wire from the junk yard... extended using soldering... NEVER had problems

quick question for TheMAN

does you CAPSLOCK just randomly switch ON and off while you're typing and YOU just said **** it?

hahaha continue...

GOOD crimps are at least as good as soldering, both continuity-wise and strength-wise. That is the part of the reason that the connections in aircraft are made using crimps. However, GOOD splices require the correct crimp tool and correctly sized connectors. And most people use pliers and over-sized connectors, which results in really crappy connections.

Most people can produce an acceptable solder joint with only a bit of practice.

So I would argue that while crimping CAN result in the better connection it often does not, and most people should stick to soldering. Soldering also has the potential benefit of resulting in a more compact splice. Which a real benefit in places like under the dash when you want to re-bundle wires. And you don't need a drawer-full of different size connectors --- solder is pretty much "one size fits all".

Personally, I do use crimps, but I spent $100 for a used pro-grade crimp tool.

so can we agree that for something like $30, the extension cable is a good idea and idiot proof...as well as cost effective? lol

Yup!

And it has the nice side benefit of being able to be put back to 100% stock if the need arises.

for something this important, you trust butt connectors? They are NEVER reliable against vibrations, movements, or heat cycling... especially since they lack weather proofing

soldering does NOT screw up resistance as much as butt connectors making a crap connection

and for O2 sensor or MAF wiring being extended by just splicing.... it's stupid because those wires are typically shielded, against electromagnetic and radio interference... just tacking on normal wires takes away this protection and screws up the readings!

when i read your posts all i can think is how much it must suck to have a huge stick shoved up your ass... chill the f**k out bro we are just here to help each other

and that stick keeps hitting the caps lock button

Never reliable eh, they why the hell does are solder joints not allowed in standard electrical practise. Not reliable when the crimp connector is heat made of a weather sealing and heat rated material. Not to mention how that you extended those shielded wires with solder how did you extend the shield. When the HELL have you ever seen sheilded MAF wires on a modern Mazda or any car for that matter. That POS 240's computer could barely tell the difference between 0.1V unlike modern Mazdas. Further more why would MAF wires be shielded in the first place, its not Hall effect tranducer, they are resistive type transducers. Guess what radio and electromagnetic waves don't effect resistance. Even on that POS 240, your extra resistance from soler just made the car run a leaner/richer depending on the signal, so of course it would work just fine the car was ****ed to begin with.


The next time you want to say my soldering sucks lets keep in mind who here has a 309A, I doubt it's you. Soldering is now mainly only used in plumbing. Since you like working on POS cars and love solder, I guess I know what you do for a living.

I trust butt connectors with my life yeah. I butt connect the piss out of the trucks at work. They go through much harsher conditions than cars do and on a daily basis. If they're good for a $100 000 + rig, its good enough for my car! haha
back on topic, the patch in leads are nice, i woudda like to have had em.

back on topic...

Ive never crimped in my life. I actually look at crimps and say "what a cheap job". If you know how to solder, your readings wouldnt get messed up. Your goal is to use the least bit of solder possible, while creating a solid connection. The signal will stay the same in most cases, unless you're overloading the solder to the point where you've doubled the gauge of your wire. By that time, you've taken the flexibility out of your wire which will easily corrode and deteriorate (sp?) the insulation. I used to make 02 wire extensions for a while, never once have i had a complaint.

Simply put, it must be damnnear perfect connection with minimal usage of solder. Too much heat causes too many problems.

Just my 2C.

Crimps are used as the industry standard, they are faster and more reliable then a soldered connection. I don't think they look cheap they look like a connection. Not to mention with crimps you get many different options of connectors.

I can't imagine having to cut or splice wires (or modify the sheet metal/plastic) every time I wanted to add something. My car would be swiss cheese and like someone said earlier, it's much nicer to be able to easily reverse everything and and also for troubleshooting.

So did you ever figure out if they made Mazda 3 specific o2 sensor extensions?

they do...the link from my earlier posts obviously changed since 3 yrs ago.

go to the site, and check out the brands sections...click mazda logo....profit.
