Hey guys it turns out my main 4gauge cable is too short after I needed to cut a piece off. I order about 5 more feet of it now my qustiion is which way is the best to join them? Just twisting the wires is enough?

solder is the best way. But i would use crimpless solder connection. THey will be hard to find because ur wire guage is so big .

bah I hoped to avoid soldering.

this is a thought i've had, i've never tried it and don't know how well it'd work but it's worth a try: crimp a ring terminal to both ends of the wire and then use a nut and bolt to attach the 2 rings together, then use heat shrink tubing or something to cover up the connection

if someone could say if this would work or not that'd be great

i would just get another fuse box(like the one next to the battery), that is if u have room for it were the wire is split....nice n semi clean lookin

or you could just add a fuse connection :-/ its the way you connect the same wire to itself where you need the real fuse.

And i dont know of any problems of adding a second fuse farther down the wire either.

but fuses and fuses holders cost money, not too mention he may not have the space for one where he ran the wire

well what i do, which i guess is the ghetto way, i wrap both of the wires together and then cover it with a lot of electircal tape.

I would not wrap the wires together. Go get another fuse block, or a terminal block and do it that way. Do not scrimp, or you might not like the results.

solder, weld it together. other wise just get a longer run.
