How to DIY - add access holes for LVB 12v battery connection points & HV Disconnect Relay for Safety

[AHoss75]

The template for the holes is in this post here:

Print it at 100% scale.

I don't have a template for the custom 3D printed hole covers if that's what you're asking.

Nope, ths is what I was looking for, thanks!

This one is interesting & neat as well, but am unclear as to how it attaches to the battery terminal.

This is my install. Details are at https://www.macheforum.com/site/threads/frunk-tub-removed-pics.12094/

yes, very neat, BUT small ga wire intended only for light charge current during FDRS or trickle charge. My goal was to use 2ga wire of up to 1500watt power output.

First mod completed!

not too bad.... they fit.

if you go bigger than 2" hole, it will be hard to find a plug. I thought about cutting a door and adding a hinge, but that's more involved than a hole saw on a drill.

I’m thinking about buying a second cover and experimenting with it.

There is a rumor over at Jalopnik that we hold cockfights rather than shrimp cocktail in the Mach-E's frunk.

How about shrimp cockfights

My take on the access ports.

I chose to run smaller gauge wire. You can attach some really big cables to that jump point. That jump point is sufficient to crank over a 600+ cube engine with 14:1 compression if you run big enough cables. I’ve personally spun some 535” engines over with one of those through 14’ of cable in the car, plus the length of the jumpers.

Just did this mod today on my 2022. Thanks!

Yes. Thanks for all the help here. Got my son to 3D print some covers. All good.

This might have been answered in the previous 18 pages, and I've looked through 70% of them.

Can these holes be drilled CAREFULLY and SLOWLY without having to remove the frunk panel and drilled in place? The 2 inch saw is wider than the contact points, so if one doesn't push too hard, the saw should do its thing. No?

I would not recommend doing it in place. I drilled them on my work bench supported by some wood blocks and rags. I might have gently clamped it. One reason I didn't want plastic bits to shoot all over and into the vent holes. Yes drill carefully but not super slow because you will be going through reinforcement ribs not just a flat plate.

Also I would make 2.5" holes and use plugs like this: https://www.amazon.com/dp/B00MN6GQIY

Thank you Steve. That looks awesome. I see that you didn't drill the 3rd hole for the disconnect.

Yes with the 2.5" hole the - and disconnect are both accessible.

I've been present when the panels were hole sawed while in place. If you're careful you will only leave plastic shavings in the car. Since this isn't the route I took, I personally have not done this. I took my panels out since I was affixing machine screw receivers for fastening my jump point and reinforcing the bosses around the machine screw receivers.
