By asking "hows it wired" I meant did you just run the hot & ground straight to the main battery? I am guessing the alternator charges the main and in turn the secondary, is that correct? Lemme know, I just wanna do it right.

 

haha, I would have to agree you were pushing some componentry, what with a computer and all that stuff! I guess I may be picking up a yellow top to run as a second to my sears diehard gold until I can replace IT with a red top, seeing as how it looks like the stock alt should be able to handle it. I gotta find somewhere to mount the yellow top though, haha, maybe it's time for the ORS manual hub swap and ADD removal so I can make room under the hood where the vacuum unit is/was, .

 

Here is pretty much all the info you need...

Stock alternator is plenty of power in my opinion. Especially with the yellow. I run my winch with truck off and have plenty of power to spare. I did replace my alternator recently (died when engine blew)...just replaced it with lifetime waranty from autozone. Its same as stock. I get 2 free replacements out of the deal. Figure if for some reason it ever goes bad...I still have to kill 2 more. Hopefully, high amp alternators will be down in $$$ after that happens

Also make sure you use good wire. I use zero guage for both my batteries. Alows for best efficency...

 

I have the Blue Top in my 4Runner & it can handle every accessory I have. It is well worth the $$$.
