Hiya everyone
I'm gonna be putting in a battery disconnect on my '81, one of the big, red-keyed deals, hopefully tonight. Where have you put yours, and how did you run the cables? Did you splice the existing cable, run new cable, etc etc?
I was thinking of somewhere easy to reach, like on the console or under dash, but somewhere near the battery itself seems easiest. It's a side terminal, and theres no real room for one of those green-knobbed shut-offs, so I opted for the other and now I have to mount it somewhere.
Ideas?
Not sure if this is helpful... on my '71 I put the battery disconnect on my battery. It attaches to a battery post, then my cable attaches to the disconnect switch.

I have hooked mine up on the battery post as well.
I found some blade type at Advanced auto that work pretty good but there is not much clearance in the battery well.
I think he has the plastic key type that OReilly's sells.
I have one like that that I have not installed yet. I thought I would attach the leads under the center glove box and mount it inside the jack compartment with a metal angle. You could probably come in through the
back compartment behind the seat also.
Let me know if you come up with a good solution. I have been thinking about mounting that "plastic key" disconnect for a while.
I have a 75 in the shop and he put his (red key type)in the battery box with the key protruding into the center compartment.Works good just open center box to turn on.I have installed a bunch of the greeen **** ones but I do a little mod to them to keep them from seperating.

I will be installing a red key type on my 79. I will be running a new ground cable. I think I will mount it right above the center console on the storage wall. It will be easy for me to access daily and easy to run the cables. The base is black and I have black carpet so it wont show all that much when the key is pulled out. I will post pics when I get around to actually installing it.
Ahh all good ideas - I see in the last pic the disconnect is attached to the negative terminal - I always thought it should be on the positive side?
Doesn't matter which side, just as long as you get a complete disconnect. I mounted mine through the battery box with key pointing forward, the lugs pointing at the drivers side halfshaft. One cable from the negative post to switch, the other from the frame to the switch.
Cable colors are not indicative of polarity in the photo.
Ahh all good ideas - I see in the last pic the disconnect is attatched to the negative terminal - I always thought it should be on the positive side?
As I understand it, by putting the switch on the positive side, you run the risk of creating a spark if you accidently touch the blade to any ground. By putting it on the ground side, if you touch anything to ground, nothing happens. I have a blade style and mine is on the ground cable.
I think most here do it to make disconnecting the battery easy when they're working on the car.
I guess when you have a 40 year old car, anything that makes working on it easier is a big help.

I ran my negative lead to the compartment behind the passenger seat and installed the switch in there. I could lift the door, insert the key and turn it on with little effort. Same for removing it.

Mine is on my positive terminal. BTW, mine has a **** I can remove to 'disable' the start circuit.
I ran a few posts a while back on this subject but never really followed thru with it as it seemed like their were other more effective anti-theft measures out there.
Still not sure what I plan on doing. But I guess I better figure it out before I cut my positive cable to length.
Merlin, any pics of the switch your going to use? link to a website to purchase ect???
Also, whats the minimum rating you would safely suggest for a cutoff switch with a removable key? Alot of the ones on the market have low ratings. At startup the switch needs to handle a good amount of voltage.
I installed the red key style one. I drilled a hole from behind drivers seat near console into battery compartment then pushed the round receiver through hole towards seat and attached with cover ring, sealer and screws. Then I cut a hole in carpet, slid over round receiver and used a black zip tie as a way to keep carpet from sliding back off. With the padded armrest in place, you can't see the lever which I dipped in that black rubber stuff you recoat plier handles with. To disconnect, I have to lift up armrest and flip switch. I used a short heavy gage battery cable from disconnect to battery hot.
OK, so when I get home, after making dinner, eating dinner, doing dishes, playing with the dog and 7 year old and rewiring my trailer, I'm going to:
- buy a short section of cable from Autopepboyzone, find a convenient location near the battery, and install previously aforementioned switch as neat and secure as possible.
- try to remember to take a few pics too
Would running a small lead from the 'constant power' of my radio to the positive terminal be a good idea to keep my clock and presets? I'd throw in a fuse for good measure. I read somewhere that a small gauge wire wouldn't harm anything and would use very little juice - true?

I'm thinking of doing the same way. There was a thread on the forum in the past few months about this and one of the forum members had done this way. Looked good and very accessible!!!
If I ever have a short and electrical fire, accessible disconnect would be very important to me.
