O2 sensor extension cable

[TheMAN]

yeah, solider screws up resistances...i just butt connected and shrink tubed mine...no issues

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!
