Alternator Output Wire Upgrade Questions.

Have the Cable/Wire to Do It & would Like to Upgrade my Alternator Output to 4GA.
I have a '96 Cherokee XJ 2 Door w/4.0 HO I-6 & 117A Alternator.

My Questions Are :
1) Can I Safely Run the 4GA from the Alternator Straight to the Post On the PCM w/ the Pos.(+) Battery Cable?
This Is Where the Stock Cable w/ 10GA Fusable Link Is Connected.
(My PCM Has One Post)
OR.....
2) Can I Run it Straight to the Pos.(+) Battery Clamp/Terminal?
And...
3) Do I/Will I NEED to Install an Inline Fuze or Breaker for Either Way?
(Does or Has Anyone Successfully Done this Without one?)
4) What's the Safest/Best Way to Do This Upgrade?

Have Read Various Posts Here & on Other Jeep Forums.
Everyone seems to be Using a Mega Fuze or Circuit Breaker.
Was just Wondering if a Straight Hookup would be Reliable/Safe.

run a fused link to the battery and separate links from the battery to the PDC and starter

run a fuse that is close to max alternator output

some people use maxi fuse, some people use ANL fuse, depends on preference and what's available

ehall,
Just Purchased a Waterproof 4GA In-Line ANL Fuse Holder & 150A ANL Fuse.
It'll be Here Next Week.
Thanx for the Quick Reply.
I figure: It's Better to B Safe than Sorry.
My '96 XJ Already Had the 4Ga Cable Upgrades on the Rest of the Battery Cables.
Alternator Is the Only one I Found w/ 6GA Wire.
Also Gonna Upgrade the Firewall Ground Strap w/ 4GA Copper Battery Cable.
Looks Like it's pretty Corroded.
I've Already Grounded the Battery Directly to the Chassis too.
Maybe this Will Help w/ Voltage Drop when using Fog Lights, Hi-Beams & Heater w/ Stereo On.
Thanx Again,

You want ground wires for battery-to-body, body-to-engine, and engine-to-battery. That way you are still fully covered if any of them fails.

Got Ya,
Already Have 4GA from the Battery to the Block.
Still Need to Look at the Starter Cable, But, I think it's 4GA Already.
Alt Wire & Block 2 Chassis are the Only Questionable ones Now.
