What is recommended wire splicing method?

Question

Hi all!

I'd like to know recommended wire splicing method. I'm electrician and just got Evo-All and Flash-link plus separate remote starter to go into my wife's 2010 RAV4 (it has a dot on the key so no Evo-One for me...)

Is soldering the best way? And then heat shrink? Or there is a better way?

Thanks!!!

Answer 1

soldiering is the best way for all small wires and the poke and twist metod for all large wires you want to ensure that you do not use any scotchlock connectors as they will cause you issues.

Thanks! Do you cut small wires before you solder add-on wire or you just remove insulation from original wire and then solder the end of the new one? Thanks

I think this is a philosphical issue, and people conflate crimping with those colored butt connectors and cheap crimping tools.

Think about this for a second -- none of the pins on any of your OEM harnesses are assembled with solder.  Fortin doesn't solder the pins on their T-harnesses (they're crimped).   The exception might be the high current connections at your ignition swith.

There's nothing to prevent you from aquiring the proper tooling to crimp AMP-style pinning in the same fashion as the vehicle manufacturer.

Just food for thought.

I would say, solder any big fat guage wires. (old GM, Dodges etc)

Poke n Twist small guage.

Poke n Twist anything that is data.

 

Crimps and solder is really only as good as the person behind the tool itself :D
