Holy Grail Labs Blade Fuse Box Replacement

[Galahad]

I got all the units built for existing orders and I'll have them in the mail tomorrow. The preorder discount ends after May 31st so buy soon if you're looking to get one at the cheaper price. Very excited to be getting these to people!

I can’t believe I missed this deal. I was following this and had a calendar reminder but still missed the preorder. Ugh!

Check out the new video we just posted to YouTube on our new 2002 Blade-Fuse Boxes, it has general information and some installation tips. A written install guide can be found on our support page here.

I just started to install the HGL fuse box for my 73 tii. I pulled the harness out before body and paint so I'm following my photos and the wiring diagram for installation. The HGL terminal/color code layout from OEM is very different (like 180 degrees off).  To be clear, should I follow the HGL terminal designations and forget the original order?

Could you reach out to us with some details? I believe you should be following what's on the new unit but I'd like to double check since you're in a bit of a unique situation. Email is support (at) holygraillabs (dot) com

I sent an email to you yesterday after this post.  We'll figure it out.

I installed my on a pre 73 car with no issues.  All terminals were as per the old box and correct per the wiring diagram.

Installed in my 1976.  Great product and already seeing benefits - installation was easy - 30 minutes.  Taking pictures before hand made it easy to follow along.

Great to hear install went well! Thank you for the feedback

Missed the preorder discount window due to funds but got mine ordered finally. Looking forward to it.

I'm a computer geek so ordered one for my '74...

Received the fuse box for my '74tii from Holy Grail Labs.  Easy install and works great!

After checking out the LEDs, I toggled the little dip switch so that the LEDs don't stay ON.  

Pretty cool...

I'll throw my testimonial into the ring as well - received my new fuse box from HGL a few weeks ago, but only just found the time to install it (along with a few other "while we're in there" bits and bobs).  It's a really gorgeous piece of kit, and like JohnS, I appreciate the telltale LEDs for circuit status (particularly the red "blown fuse" idiot light feature, shown below with the #2 circuit "forced" open).

 

Took me no more than 35 minutes to install on my '76, with the most arduous part being the minor connector block modification required to clear the new ground spade...oh and the fact that I lost track of where the switched power supply connection for my aftermarket stereo was supposed to land 🙃

 

Perhaps unsurprisingly, I'm noticing a higher voltage reading on my dash gauge through the HGL box than through the old bullet fuse box - approximately 13.8V vs. 13.4V.  Suffice to say there was a little more voltage drop through those crusty old bullet fuses!  Kudos to @Galahad for a super product, many thanks for bringing it to the masses!
