[GPZ900R] Introducing Daytona’s “D-UNIT WR mini”! Refreshing the messy wiring while we’re at it with accident repairs

I think today’s forecast was supposed to change from rain to cloudy…
But it’s suddenly gotten so cold. It feels like minus 10 degrees.

I wonder if there are many people who are pushing through without pulling out their long sleeves at this point…
A while back, I thought the D-UNIT+ was the strongest thing ever.
Time passes, and similar products from other manufacturers have been coming out.
But even so, small is still justice! That’s right! That’s the Daytona D-UNIT WR MINI.

If you’re going to redo the wiring, I recommend this one.

Electrical products lack visibility of the whole picture

Every product focuses mainly on the unit itself, and the volume of wiring is unclear.
By the way, every product has wiring that’s surprisingly long at first glance.

Short won’t reach. Long is safe—that’s the theory.
Basically, if you install it without shortening the wiring, it becomes a yakisoba party.

Once installed, it’s probably never removed from that location “Simple and easy to maintain” is the key point.
Electricity is invisible infrastructure. You definitely want to make sure it’s done right.

Power management items like D-UNIT are essential

It’s a very convenient item, but there are quite a few mysterious aspects to it.

The fork-shaped terminal that should be co-tightened to the battery.
Whether to slip it under the terminal nut or not, the directional freedom is…
If it’s directly below the terminal bolt, you’d need a washer.
If it’s sandwiched on the terminal, the contact area decreases.

Basically, it’s better not to use it as-is…

The approximately 3sq is a drawback considering layout flexibility.
The D-UNIT WR MINI can supply up to 20A, but it comes with unnecessarily thick 3SQ wiring.
With this capacity, 2SQ would be more than sufficient.

I suspect they made it thicker and bulkier considering the possibility of routing it all the way to the headlight area.
But
you shouldn’t route it that far away
If you place a fuse upstream of this red lead (closest to the battery), it’s safe.
However, I think fewer people actually do this.
Co-tightening to the battery + (constant power) is risky—if the insulation breaks and contacts ground, it’s a disaster.
It will discharge rapidly until the battery is empty, and most likely it will catch fire…

The golden rule is to keep it as short as possible and mount it near the battery.
Basically, there’s almost no point in making it thick and long… ( ；∀；)

Reducing disconnect actions and improving visibility makes future maintenance easier.
Using this with the original Giboshi connectors… do you use them?
DIY crimped terminals “Male and female Giboshi connectors usually come loose during disconnection”
It would be easier if they came as 110 connectors from the start.

I think it’s better to minimize Giboshi connections as much as possible

Make a plate and mount it securely—

And if possible, avoid fixing the back with nuts.
When you proceed with work in a way that reduces the number of tools needed, things get easier and easier.

Despite all my rambling, it’s currently the most compact and powerful power management item.
Only three circuits? No way
7.5A×2 & 5A×1, so you can use as many outlets as you want within capacity.
Of course, you’ll need individual fuses for each.

Processing each part.

For this type of aftermarket item, “wiring length that can be quickly disconnected” is the key.

If everything is long when you remove it, it becomes a hassle.
Think about removing something before you install it and I think that’s really good.

Lately, materials have really improved in every way and become easier to obtain.
This old guy is amazed!

Oh, I only use Sanichi heat shrink tubing…

Straight corrugated tube insertion

It only gets used about once a month, but it’s incredibly handy to have.

When you buy on Amazon, there’s this mysterious “Product $20 Shipping $700”
Wouldn’t $720 free shipping be easier to buy?

That’s how it works.
It’s a real tool! and I’m subtly impressed (‘◇’)ゞ

Wiring color is better when invisible, and it’s safer with insulation.
Plus, since it’s an outer sleeve, disconnection is convenient—that’s the point!

Temporarily secured with yellow reusable ties.

I use this to prevent forgotten installation.
Lately I’ve been using reusable ties to secure wiring.
Permanent fixing uses regular cable ties (insulation locks).
For locations where I need to disconnect and for gentle fixing, I use reusable ties.

I hate that wasteful feeling of cutting and throwing away, so I try to reduce waste and stock materials.

Since it’s spread out in multiple locations rather than concentrated in one place, I think it looks pretty clean.

We’re stopping for now because we’re short on some electrical materials.
