Glass to spade fuse questions

I've started the process of changing over from glass to spade fuses. But it looks like the conversion isn't the 1:1 that I was thinking. There are two conditions that the spade fuse box doesn't seem equipped for.

1- Multiple wires coming into the OEM terminal - I am not able to get a good purchase when the two wires combined. Do I need a larger terminal to accommodate the gauge or make a new circuit?

2. There are a few circuits that have three wires going into terminals one side of the fuse and the other side has one terminal.

Pics are attached. Any help is appreciated as I am new to automotive wiring.

I'm having similar questions after switching to a blade fuse panel as well. I'm interested in what the experts have to say about these issues.

Thanks. I picked up a similar tool and it makes the process much easier. Guess I didn't account for these edge cases though.

Get a ratcheting crimper...much better connections and a good stripping tool...took me about an hour to do the whole fuse panel switch with real nice tight crimps...

What fuse holder did you use there? Was it a direct-fit into the panel, or did you have to cut at all? Looks good....one of these days I need to do mine!

I used a AMR3138 for the fuse box and replacement fuse box from ebay

The fuse block was a direct drop in with the new fuse holder.

Best $100 you can spend on an early truck. Nicely done.

I like smart fuses with an led in them so when something blows and its a cold and rainy night all you have to do is remove the cover and there it is shining @ you eliminating any guess work and the need for a flash light. Whomever invented smart fuses must have owned a defender....

If any of you have used this... I have the fuse box from the '93 NAS 110, should I order one of these, or keep and reuse the '93 fuse box in my rebuild/rewire of the '88 truck?

EDIT:
Did you have any issues using that eBay seller, or coming from UK?
If anyone recommends another option for a replacement fuse box, what would it be? (I'm using the 6 point Blue Sea box for my accessories, and it will be mounted with my batteries under my seat box.)

Looks like you did a good job on this, makes me happy to know I will only spend 7-8 days on this job.... ...that seems to by my typical conversion time from normal job length to what it will actually take me to do the same job.

The ratcheting crimper is a must. I purchased a cheap o on from Amazon, but it ruined a few crimps. I ended up with one from I Swiss which was much better. I also got some extra terminals to practice on before I moved up the real ones. The biggest challenge I had some figuring out the previous owners fuse box skullduggery.

Where's the best place to get all the smart fuses? Buy piece by piece at the local auto parts store? Online?

Thanks

Nick,

Looks great. I have all of the tools and parts (I think). How did you end up handling the two into one instances? Were you able to fit two wires into the standard crimp or did you need a different crimp? I've got the Astro ratcheting wire crimpers if that helps.

Thanks,
Greg

I was able to force them into one, but I ruined a few terminals getting it just right. In hindsight I should have probably looked harder for the next size terminal. You can muscle it, but it takes a little practice.
