Alternator upgrade wiring

[FearlessFoe]

I have a 92 C1500.. I am looking to install dual electric cooling fans to help cope with the gas prices these days.. I also have aftermarket fog lights and a fairly decent sized stereo system. I am looking to upgrade from the 105 amp alternator to a new 140. I just want to know if anyone can help me with the wiring. Will I just have to run a thicker guage wire to the junction block? Or will I also have to run a thicker wire from the junction block to the battery? Should I run a charger cable from the alt. directly to the battery? Thanks!

The alt will supply the power you need to your assy as they are, make sure that all your grounds are good and nothing is loose, a spare starting battery (deep cycle marine) will help keeep the juices flowing and the sounds loud. No extra wiring is needed except what came with the setup for the assy.
