There's movement on many fronts with the House Cat lately. Bodywork, wiring, moar.![](https://www.miataturbo.net/attachments/build-threads-57/171349-house-cat-80-20160512_162139_d2e72006811b0e97db7ad950ce5100aefd6ccd5c.jpg?dateline=1463108777)

949 6UL's 17x9, with 235/40 NT-01's. That rubber feels like it could crawl up a wall it's so sticky.

Lots of toggles. Seats on this one will be heated.
Speedhut gauges, including GPS speedometer with built in odometer. The aluminum mounting plate will be crinkle coated.

Wiring. Trying to hide most of it, although all of it is impossibly thin MilSpec silver coated stuff.

Here is a place for oversized clutches and plates so you can get more preload out of the diff. You can also shim it yourself and achieve a similar result but, it will require some trial and error. If you have the money go for the Giken. Diff Mount, LSD, Torsen, Rear Oils

Fuses are good.
You need fuses.
Fuses don't have to be made of fuse. On airplanes and some boats, circuit breakers are used instead. We also use circuit breakers in things like TV news trucks and military vehicles.
Fuses can also be made out of things like SmartWire, though that specific solution is profoundly expensive and needlessly complex for most applications.
ATM (mini) style breakers are fairly inexpensive and widely available, although they do tend to be rather longer than conventional ATM fuses.

ATM, ATC, MAX, Glass Tube Footprints, Circuit Breakers
Mini Circuit Breakers - Wiring Products
Stud-type breakers are also widely available for those circuits such as the Main Fuse which require them.
Take note of the various reset styles. Some are auto-resetting (and will continuously cycle on and off in the presence of an overcurrent situation), some are "modified" auto reset, and will remain open until the overcurrent is removed, and some are manual-resetting.
Fully manual breakers, the sort where you can deliberately switch the circuit off, are generally not available in the ATM footprint, sadly.
But all of these things are better than nothing.

Joe, he isn't going unprotected. He is using a PDM (Power distribution module). PDMs have replaced fusing in all high level motorsports for years now. A good Motec PDM can keep a race car running with a failing component that would pop a fuse long enough for repairs or perhaps limping the car to the end of a race. They vary in how they work, but generally they work like highly intelligent fusing. They detect faults and can modulate the current for specific purposes.
I would personally have a large breaker for the alternator and battery to smartwire system.
In low budget racing, we usually just go with auto-reset breakers over fuses.
Generally speaking and without nitpicking, the wiring work looks good. Concentric wiring and a few other little tricks indicate they have experience and knowledge.

The highly evolved off-road industry down here are using SmartWire stuff on their wildly expensive trucks. They run redundant setups on things like the fuel pump. If the pump dies, SmartWire tries to run it 100 times (pick a number), which takes about a second. If it doesn't work then the back-up fuel pump turns on automagically. I'm not taking advantage of that type feature, mainly because I don't need it for this car.
My next decision is whether to Skunk or not to Skunk. Throttle body. Thoughts?

Emphasis on the latter half of the sentence. SmartWire and similar technologies are very cool. Emilio had one mostly installed on Crusher when I was working on its ECU during the initial construction and first start.
The point of the post was simply that there is an inexpensive, simple and highly-reliable middle ground between thermal fuses and expensive PDM systems which is largely unacknowledged in the automotive aftermarket, despite having been a de-facto standard for many decades in aviation, maritime, and industrial applications.
