Fuse panel upgrade
I have a 74 911...after working on the headlights and those pesky german fuses...is there a kit or something that we can replace the fuse and relay panel in the truck with...My idea is something that uses the current modern fuses.

I think someone here posted an upgrade using the ATO/ATC type blade fuses.
on edit - found this --> Fuse panel upgrade to ATO type

One issue with this upgrade is if you can make the mods equivalent to an OEM install and not disturb the original factory wiring positions. Otherwise, this upgrade is only good for you and only then based on your memory of what you did (unless you document every modification). IOW, will your auto tech give you the evil eye if/when you bring your car in for electrical diagnosis?

Fuse Panel Upgrade
When I built the ATO fuse panel for my SC coupe, I replicated the original fuse positions and added 3 extra fuses on the back end. That way, any diagnosis that may have to be done in the future can follow the original wiring schematic. The extra fuses are for some add ons like an oil cooler fan, etc. Since I completed the change to ATO fuses, I have only had one electrical issue and that was caused by a poor splice at the fuse box (my fault). It can be done, just be careful, lable all the wires as to position before removing and be certain to understand what each and every wire does before beginning. Also, keep in mind that there are some hardwired jumpers on the back side of the fuse blocks that will have to be duplicated. Good luck with your project.

Very Interesting
Did you build it with individual fuse holders or in racks?
Can you provide a picture for reference?

911 Fuse upgrade....
I built my own panel, designed so that it would mount to the stock base. The fuse holders came from Norway by way of a PP board member. Send me a PM with your regular email address and I will send you a set of files with the design for the fuse holder base and some wiring info. The files are done in Excel and are easier to send directly rather than try to put them on this BB. My car is a 1980 SC so you would need to compare what I used with the actual wiring on your car. The job is not hard, just tedious. On the plus side, it cleared up a number of small electrical gremlins that seemed to come and go at will.

Summit and JEGS sell fuse panels that could probably be adapted. It wouldn't be easy though because of the number of wires. One thing to do is to replace all the fuses with new ones of the same type. These types of fuses can be bad (work sporadically) even when not blown. Even if they don't look like they have much corrosion, they may not work properly.

Fred and Gsmith, did you use a ground bus system for your project? Thanks for the great write-up BTW.
Fred, PM sent.

No I didn't kept it stock except for changing the type of fuse used. Probably why I still have some of my electrical gremlins that I have had for years I am sure they are grounding issues.

Fuse upgrade......
No, I did not use a ground buss. I duplicated what was on the original fuse blocks with one exception. That exception was to divide the feed for the evaporator fan and the front condenser fan. That particular load was separated to keep the load below 20 amps which is the max load rating for the fuse holders.
