Discussion and questions related to the course Motorsport Wiring Fundamentals
this block make planning out your power circuit a breeze.
Ahhh, I saw a picture of one of these pop up in a FB post recently, very interesting!
I have been using Bussman RTMR series ISO280 fuse/relay blocks. They are similar size, take the same fuses and looks like same relays. But allow massive flexibility in how they are wired and configured. And take more fuses/circuits aswell. They are good in the flexibility of configuring them in such a compact form. And neat because all wires exit rear. The downside is its very time consuming to terminate all the interconnects between fuse and relay etc, and 280 terminals arent great for that much current.
I have used one before on a simple club level car three years ago.
I found it to quite good for that application, but times and PDMs are a much better way to go when you are paying someone to wire the car.
So for DIY would be good, but think the Bussman system is probably a better way to go in DIY
