Ric,

I buy all of my wiring crap here: http://www.wranglernw.com/

download the full catalog available online and then call them to place the order. They're pretty quick on shipping them and the quality is awesome. They have connectors for whatever you need so just ask them. They'll be able to help you out. All you need to do is just figure out how much cable you want to buy

0/1 ga or 2 ga all around should suffice. I have 0/1 ga but it's pretty overkill (but i love overkill)

good luck!

so was this big 3 upgrade actually done, did it help?

I plan on doing it but have 2 questions.

where the Heck is the engine block to frame ground ?
and
do I need to go from + bat to alt OR + bat to fuse block?

There is no engine to frame ground on the 3.4.
It is engine to body (look on the passenger side of the engine right behind the intake plenum on the passenger side, there is a wire from the back of the block to the fire wall.

This you could probably move to the frame, just run it from that spot down to the frame.

Reason I know this is cause I was all over the engine last night when I was trying to work my starter. I presume that's what everyone else has done.

sweet probably why I couldn't locate the wire I was looking for a steel braided wire going to the frame. the firewall is suitable is a ground in the Big 3 as the battery ground connects to it.

Can you guys share the lengths for each wire? I don't want to have to take all of them off and then head to the store for the cable.

Also, I thought I'd share what I do to attach those large eyelets to the cable. I don't have a heavy duty crimper (they are ridiculously expensive ), but I do have a little butane torch. What I do is roll up a ball of electrical solder (the size depends on the cable diameter, anywhere from a pea to a marble size) and place it in the eyelet. Hold the eyelet with some pliers and melt the solder with the torch. Then insert the cable. Before hand I trim the cable cover back so it fits right against the eyelet collar. It's a better connection because it can't corrode nearly as much as an open crimp.

I scavenged these photos from another forum, should provide a visual for Erich's excellent verbal description:

Yarrr, no sweat, I started reading and thought to myself that I'd *just* seen a write-up on that somewhere...
