One of the upgrades I needed to do on my Fury was in the power feed area. Several new pieces, like the EFI module, ignition module, amp, fuel pump, etc. state that the power leads should be connected directly to the battery. That can make a real mess at the battery terminal if you actually do it.
I looked around at some modern cars and most, like Dodge, use a fairly large junction box as a common connection point. That's fine but it takes up a lot of room underhood. But, it turns out most Nissans/Infinitis use a very compact fusible link setup. There are a few different versions - the one used in my wife's 2007 FX35 turned out to be what I needed.
These links contain multiple circuits directly off the battery. I wound up using the un-fused link for the starter, the 140 amp link for the 140 amp alternator, a 60 amp link for the ignition/interior, and another 60 amp link for the amp and fuel pump. The interior is of course now fed without going through the bulkhead.
Two of the links I did not need but are there in case I need them later. The whole fusible link costs $15-50 depending on which model you use.
It's not Mopar, and it's not original, but for a 'modernized' system it's hard to beat these.

Very cool! These cars have classic lines and great sentimental visual appeal, but there is nothing cool about living with the outdated electrical design just to keep them stock. They deserve some modern upgrades that make them safe and roadworthy as long as it's integrated cleanly. I like it!

That's a lot slicker than having a bunch of eyelets hanging off the clamp bolt and starter relay like I have! Why did that model work for you, the right physical shape or number/rating of connections? (wondering what the other choices are)

As far as I know, all of them have 4 or 5 fusible links. Depending on the model of car they were used in, some have 40, 60, 80, 100, 120, 140 amp,etc. links.
They all seem to be the same physical size. I did not do tonms of research but I don't know of any other company that uses them. I can tell you my Lexus uses a Dodge-like connection box so I suspect all Toyota/Lexus vehicles do so as well.
I used the one I did because it had a non-fused stud for my starter. Some of them must connect the starter some other way because they don't have this feature. Or course, you can't fuse the starter since it pulls so many amps. I also used it because the smaller map links worked well with what I expected the current draw to be. For example, the fuel pump (11 amps) and the amp (40 amps) are fed off a 60 amp link. The 140 amp link matched up well with the 140 amp alternator.
The hardest part was finding the connectors used to plug into the bottom of the fusible link where the lower amp links are. Infiniti does not sell them except as part of the entire engine wiring harness which is big bucks. But, most wrecking yards know they will never sell an engine harness so they are willing to chop off the connectors and usually do it fairly cheap.

Did you buy the terminal block with the fusible links new from the dealer? Got a part number? If one fusible link blows, are they individually replaceable?

I bought the positive battery terminal, the plastic cover, and the fusible link block from infinitiusa.com. They sell OEM parts at lower prices than the dealer. The plastic cover shown (wherever my pics went?) they sent is the wrong one so I will have to get the right one.
The like to keep the part number 'secret', I suppose to keep people from shopping around. So the website does not show them. I ordered one for a 2007 Infiniti FX35 AWD with intelligent cruise and the nav system.
I wondered about the links also but I haven't taken time to study if they can be individually replaced. My guess is you could get them out (they don't look molded in) but I do not think you can buy individual replacements. This doesn't bother me a lot as I doubt I will ever blow one anyway. I will probably buy a spare block to keep on hand just in case. They're not that expensive.
That looks AWESOME! I have my battery in the trunk,but i guess you could mount this on the starter relay somehow. I'll have to put some thought into this. Looks like an easy upgrade. !thumb

Correction - I bought the link and terminal from InfinitiPartsUSA.com.
The terminal is Part No. 24380-7F000 and the fusible link block is Part No. 24380-79913. <span class='smallblacktext'>[ Edited Sun Oct 23 2011, 10:26PM ]</span>
