Good info., but does anyone know what  the amp rating is on the black and green wire?

Thanks .....Ron

Here's some good reading.  They don't have an "amp rating", generally.  Probably have better luck calculating the max amperage appropriate for the wire gauge.  Start from scratch.

I just picked these from the internet.  Littelfuse and Digikey are well-established names.  SAE, of course.  Omega has been around forever and used to publish a paper catalog that was basically a primer on all things electronic.

The majority of info on the FLWX sheet was the same as the FTX so I didn't bother to duplicate the translation. Almost everything on the FLWX datasheet was the same as the FTX, so I didn't bother to do both. About the only thing that was different was the color column, so I did that one and didn't bother duplicating the effort on the rest of the info. Guess I should have made that clear and saved you the trouble. 

As for the amperage rating, the amperage that it can handle depends (among other things) on ambient temperature and the length of the link. My read on the situation is that datasheet isn't for fusible links. It's for wire designed to be turned into fusible links.

That said, I agree... I think they could have specified a typical case based on a fixed length at a specific ambient temperature. Would have made a convenient column to include.

Here's the datasheets that I translated earlier.

FTX series:

FLWX series (that is pretty much the same as the FTX with the exception of the color column:

Here's a couple of pics for everyone who helped hammer this topic out and bring order to the universe.

 

Nice pics. Now you just need a set of these. If I remembered your mailing address....... I was only there once.     :

Hey @Captain Obvious You planning on making more of those stickers. Hint hint.

Haha!! I could possibly be convinced to make more.

You know they aren't metric though, right?

This is an old topic tread I wonder if anybody will still see it. All the info resulted very informative and useful to start the upgrade of the fuse links for amore modern version.

Anyhow, I just have a question. I replaced the fuse links with the Maxi fuse version and respective fuse-bracket. This involved -only- cutting the four supply cables (white) and the lead cables with the power to the different control functions (white-red) and reconnecting them in the bracket. This is the only change I did. 
I have voltage signal before and after the new fuses, so all fine. The detail now is that the Amp light in the dashboard does not work and no voltage is measures (also the fuel gauge is dead). The engine cranks but does not start.

in view do the simple replacement I did all the rest should work but now something obviously is not right. 
I would appreciate an indication of something that I might not have considered.  See picture of current install.

Did things work correctly before?  Supply some history of the vehicle.  What is it?

Did you disconnect the battery before doing the work?

All worked fine and battery was disconnected. The issues I was trying to solve was faulty contacts for headlights and a stutter (electric failure just above 65mph that will stop after reducing power). All worked fine but these details

What would happen with only ground disconnected?
