So I popped the hood this afternoon to try and check things out before I upgrade the wires, well i should have known better! Does anyone have any pics after they did the big 3, also where is the engine ground wire, and I lost the battery negative wire somewhere under the air box , and I guess the power to alt wire runs across the engine somewhere, also if you did the upgrade, did you use 4gauge or 0gauge, and how many feet?
Thanks

Get a kit, like the one from Courtesy Nissan. It has detailed instructions with pics, 4 guage wires precut to required length and with connectors.

is this the kit your talking bout cause it says it for the 3.5 or does that matter

Yeah thats the one. I don't know what year your car is so I gave that as an example. The 3.5L probably matters because one of the wires needs to be grounded to the engine. You can find kits for other maxima's, like on stillen.com. Those are a bit more expensive though.

Give me a sec, I will go out and snap a few shots. Should take 15 mins with prepped wires.

This is the top of the alternator. I used all black wire due to preference, use what ever you want. This wire will go directly to the positive post on your battery.



I tried to get a good pic of the engine side of the engine/chassis ground. The bolt is directly behind the wire in the center of the pic. Man I need photoshop so I can circle things. Fortunately the ring terminal is the most shiney object in the pic.

This is a pic of the chassis side of the engine/chassis ground as well as the neg battery/chassis. I used the same bolt for both.

Sorry about the pics. Old camera, but it still gets the job done.

cool thanks, so I dont have to route the lines exactly the same as the factory lines, as long as I get the connections right? Is that correct?

filtor1

iTrader: (7)

That is correct. Route them where you want, just pay attention to possible hot spots and/or moving parts. I have the positive run along the top of the radiator. The others I just cut to fit.

Sweet thanks

Thats how I have mine as well, I just added some insulation for piece of mind

Also fuse the wire for more security

If I had to do it all over again I would definitely add a fuse as you did. Where did you add insulation?

Fast1one

iTrader: (12)

Just added it where the radiator touched the wire, there was really no way it would get hot enough to burn through the wire's insulation unless the car was burning up or something, but better safe than sorry...

I added a fuse near the alternator and another near the battery. Overkill? Probably, but I had the fuse holders laying around anyway

filtor1

Yeah, that is exact reason I didn't add one, I used them all on other projects.
