Replace blank dash switch with a voltage monitor

Hey all. I want to replace the blank switch on my dash where the ECT Power button would be with a voltage monitor like this: https://a.co/d/dFx5laA but I can't find confirmation of the switch size for that spot. I'd rather not get a cigarette lighter one. I know the part number for the ECT Power button is 84721-04010, but that hasn't helped me find a size. Any help would be great!

Pic of my dash:

 

Photo #2 on the Amazon listing gives the size.

 

I know the size of the replacement switch. I'm asking if anyone knows the exact size of the ECT Power switch so I can compare and know the replacement switch will fit without having to pop the blank out.

 

This is a pic from Meso's site, with switch dimensions. Hope this helps.

 

I just moved my Wireless Charging switch yesterday from the spot next to the cigarette lighter. I did have to file the lower left notch in the new space to make it fit. From a video I watched, it appears some minor modifications may be need depending on the switch...little filing or dremeling if new switch has protrusions.

FYI...I didn't need to modify either the far left blank (no BSM) or the space vacated by wireless charging switch for my non-OEM heated seat switches.

Why not replace the cigarette lighter with a USB/voltage display combo instead...not a plug and play unit?? That's my plans

 

This is great! Thanks!

 

I thought about that, but I know I'll never use that blank switch and it bugs me seeing nothing there.

 

Lol...good enough reasoning for me.

 

Do you have a link to the Seat Heating switch? If that fits there easily, I can probably use that size as a guide.

 

No, just bought the heated pads, switches and all as part of a package off Amazon
