New Alt. install question
I have a 200amp Alternator waiting to be installed. I need to know if I should go with 4g wire or 1/0g wire. and approx. how much will I need.
Also is there any reason I couldn't use something like this

I have very limited time to change out the Alternator and wiring, so I can't afford to be making trips back and forth to parts stores or wait for shipping on forgotten parts.
is there any other information someone could offer that would speed this process up?

4ga is the minimum I'd use for a 200a alt. (most of the places that sell them recommend 4ga ot 2ga as I remember)
You're probably going to need one piece at least 5' long to go from the alt over to the battery (at least I did on my '96 4.0 v6)
I opted to go with 1/0ga from the alt to fuse, fuse to starter relay, starter relay to battery; starter ground to frame, frame to body & body to battery negative... then 1/0 in to my distribution block for my amps, accy's.
I had to modify my battery terminals to accept two 1/0ga wires, but it worked out well. (I've been meaning to get pics of my install, but I just haven't had time...)
I believe I bought 30' total of 1/0ga and I had about 2' left over.
You might be able to find some 4ga butt connectors to add a couple of those 3' sections of 4ga together, but I don't recommend splicing large wire together.

you could use that wire.....it is designed for power transfer....
as far as the wire size is concerned, 4 gauge is plenty if you are running to the starter relay or battery.....you can run 4 gauge with 200A up to 9'.....and you wont need that much....
but you should also upgrade the solenoid to battery and solenoid to main fuse panel under the hood with 4 gauge wire also.....also, upgrade your battery to starter ground, and battery to chassie ground with 4 guage wire......you can go look at your truck to get an estimate of how much wire you will need......and make sure you have the proper amount of wire ends (and probably a few extra).....
when i get my new 200A alternator, i am going to use the 4 gaue i have in there now on my 125A Explorer alternator.....i have the wire oversized because i knew i was going to a bigger alternator.......

Welding wire, should be plenty thick, old installers trick. also solder the ends on the wires instead of crimping. solder pellets are u friend (found em at NAPA) as is mr. propane torch.
i dont see how a "how to" is needed. buy some wire, copper ends, solder pellets and a propane torch. measure, cut, solder, seal, connect, secure, double check, drive and enjoy.
i went and made rough measurements and bought an extra 5 foot. i also counted how many copper ends i would need and bought 4 extra. same with the solder pellets and shrink wrap (actually had a **** load of ****). also got my wire from a local stereo shop. cheapest 4 awg (only did a 130A swap). the welding wire is 0 awg IIRC or thicker, hehe.
that work?
