I contacted the manufacturer and indeed we qualify for a 15% discount on this cool product.
Basically the fused diode installs in the engine bay fuse box, no need to mess about with wires, solder or heat shrink...

They are $50 retail, -15%, Express post adds $10 but is optional.
Please express your interest and I shall PM you with our discount code, for your use, until the mfg closes the group buy.
Can you DIY this? Yes absolutely, and if DIY is your thing chance are you've DIY'd this already

By the way it is expensive but if you factor in all they did to get it made and where it has to ship from its not too bad.
Plus its a resetable un-blowable fuse. It will last forever.[/QUOTE]
