Default Disconnect switch

Does anyone have pictures of a disconnect switch mounted under the front seat?
I canít figure out a good way to run the cables. Thanks in advance for any responses

This is a picture looking down on the left front corner of the seat mount area on a 29 Town Sedan. The cable runs up through a hole in the floor pan and is installed in the positive ground cable. The handle is just above floor level at the front of the seat mount. I don't have access to take a better picture for a few days.

My 1930 coupe has the disconnect mounted up through a hole on the left crossmember and the cables are routed through the hole for the brake rod.
I will add a few pictures later to show the exact locations of the routing.

Thanks for the responses, the pics are a great help. But, Iím going to hijack my own thread here though. The instructions that came with my switch say not to turn the disconnect switch off before stopping the engine if itís an alternator equipped vehicle (mine is), due to ďpossibly causing alternator diode failure.Ē Iím also installing a safety fuse at the starter. Question: If the fuse blows while the car is running, wouldnít that have the same affect as turning the disconnect switch off? Iím making my car 12 Volt negative ground with an alternator.

Hi Dean,
Some serious points to think about,
1. NEVER EVER admit or suggest that you want to, or have gone to 12v, positive, negative or whatever, NEVER EVER. You will never hear the end of it. I own a 12 volt negative Model A pickup as well as a 29 Chevy and I get it from both forums

2. Seriously now, I believe you are correct, it would be the same as turning off the disconnect which. However, fuses donít normally blow and I believe, if they do, most probably on start up and only once in a blue moon. Get yourself a little mental checklist, ie, Fuel off, ign off, master off, etc

3. Alternator?(tongue in cheek again) GOTO point nr 1 and never mention it again. In fact, I am seriously considering changing my 250SL Pagoda and my E Type to 6v and generator. Maybe even the 911

Floats: That’s a great response, I love it. Thanks for enlightening me as how criminal it is to convert to a 12 Volt negative ground. I had no idea. I promise never to let it be known again. I won’t let anyone ever look under the hood and if somebody asks about it, I’ll avoid the question or lie if need be.

Dean,

I donít think anyone can tell you have a 12 volt system by looking under the hood. Even if youíre running an alternator It wonít give your secret away because many people run 6 volt alternators. The only way to tell is by looking at the battery which is safely tucked away under the floor board.
