That's more like it. Perfect. You can put the marshmallows away. You won't be needing them.
Heat shrink crimps work great. I see you can buy them at several auto places. They look odd sort of semi transparent. The ones with the glue inside are superior. http://www.google.com/products?hl=en...ed=0CDMQrQQwAg
Crimp pliers. Go buy yourself a set of Channel Lock 909 ones and throw those useless ones you got away. ( or sell them to somebody that owns a Ford or a Dodge )
Work as well as the T & B ones and are 1/10th of the cost.
Can't handle crimps? These work great too.
Use something on the bare copper wire to prevent corrosion. Penatrox or Noalox or something similar. Water and DC current don't mix. I wire can rot off in a few short hours if it gets wet. Think electrolysis. Dip you bare wire ends before you crimp.
Solder? If you can solder. It's best. but needs heat shrink over it. You can even put Penatrox on it before you shrink wrap.
Zap straps. Toss them, you need really good ones for a truck. I recommend the "Black T & B TyRaps" from a electrical wholesaler, nothing else. Or use those useless zap straps to hold your really good T & B ones in a bundle or give em to a Chevy owner. T & B Black never gets brittle. If you want it off you must cut it off period. You will not break them even if there thirty years old.
Don't scrimp on wire. It's cheap. I would not use anything smaller than 18 gauge unless you have to for some reason. I'd even avoid 18 gauge and use 16 instead. Unless you have to for some fitting reason don't bother. DC does not like traveling threw small wires very far.
