What he said (^) ... this is just a 2-wire signal that doesn't care a fig if it runs through aluminum foil or old metal coat hangers.

Polarity has nothing to do with it either so don't worry.

It WOULD be nice to make heat shrunk butt connections though .. the signal is kinda weak and if there's any water getting into those connections, then you could have troubles.​

I use the 18-22ga (red) connectors and like them much better.

Really --- there's MOSTLY 18-22ga wires in an automobile unless you need to carry bigger current.

I order these by the jar...

Thanks so much guys! All i have to worry about then is having a good strong connection!

Yes @Ravalli Surfer i have awg 14 to 16 heat shrink tubing with solder in the middle. All i have to do is heat it up with a heat gun and the solder will melt and the tubing will shrink to keep it tight.. a little bit of electrical tape around the wires too should help.

That's not really solder -- I believe it's bismuth
