I have talked with Ford about this as the ground is difficult to disconnect. I asked if a manual disconnect on the positive would work, they thought so BUT were unwilling to put it in writing.
Their reason for requiring the ground cable disconnect is because they think it is possible, if the battery is connected, for the transmission to go into gear because of vibrations from being towed down the road. If it does you won't know it until the transmission is ruined and depending on your speed and the gear it engages maybe the engine overreved and blown up.
I leave the top battery cover off and use a ratchet end wrench that has a flexible head angle. Angle it about 30 degrees and it works well. You only have to slightly loosen the nut to remove the cable. Make sure you set the car up to tow AND lock the doors before you disconnect the battery. The other doors WILL NOT LOCK except with power on. I had an extra key made to lock and unlock the door.
I have towed 5,000 mile with no problems.

|Texaswiley||I have towed my 2013 Titanium over 5,000 miles and disconnected the negative terminal. It is a bit of a pain. I'm sure the positive terminal would accomplish the same thing. They just recommend the negative for safety considerations. I met a guy towing a 2012 in Montana. He had towed it from Tenn. Asked what terminal he disconnected and he said "NEITHER one" Only problem on a long day if he forgot to turn accessories off his battery went dead. So who really knows why we're disconnecting them. I'm pretty sure you couldn't get a reliable answer from Ford. I towed an 2004 4WD Tahoe before and the manual insisted I leave the key in the 1st on position to prevent the steering wheel lock from engaging. I tried to explain to the tech guy at GM that the 2004 and later Tahoe no longer HAD A STEERING WHEEL LOCK. Response was 'you are correct but you can't be too careful'. LOL|

Thanks for the post. I didn't get a base plate yet as the tranny went out in the motor home, even before I was towing anything, so now I must admit I'm having second thoughts about towing at all. I'll probably do it, but had also considered a tow dolly, which would allow me to tow my '70 Opel GT, which only weighs 2,000 lbs. The Acme EZE Tow dolly is only 405 lbs, so that would make for a pretty lightweight set up and would allow me to tow either the Opel or the ST.
Any chance you could post a front-grill photo? If I go the base plate route I'd have to decide between Roadmaster and Blue Ox-- whichever one looks least conspicuous would be my choice-- but I can't seem to find any photos showing the Roadmaster installed on an ST.
I'm in Cottonwood/Sedona area. I get to Havasu once in awhile, so if I see a red ST I'll know who it is!
EDIT: Never mind the photo. I just noticed you have a Titanium and mine is an ST. Roadmaster doesn't appear to make a base plate for the ST yet.

|Texaswiley||Just read your post. If you haven't installed a base plate yet, I just installed a Roadmaster on my 2013. fairly straightforward install but you have to remove the front fascia, headlights and a few other misc parts. Their instructions had a few errors. Mainly forgot to mention loosening the 2 bolts on each side where the fascia and fender connect. You can get to the pass side behind the headlight the drivers side one is doable behind the headlight the other from underneath with a LOOONG extension. Also I had to reduce the spacer width on the washer bottle mount from their 1" to 5/8" so the bottle would clear my driving lights. Looks nice installed, pretty inconspicuous.|

I've heard a couple horror stories on RV forums about flat towing a Focus w/ auto-trans, but I'm not sure those guys were following the rules to the letter. There are two cables going to the negative terminal, and it is apparently important to remove both.
I'm planning to go with a manual trans just in case though. I'm waiting for Blue Ox to come up with a baseplate for the ST, which they hope to have in the next 30-60 days!

I tried a battery disconnect on the negative wire for a while and it ended up going bad. Not sure why it went bad? I took it out and just keep a 1/4" ratchet with a 10mm socket in the glove box. I quit using the cheap battery box cover and now it only takes 30 seconds to remove the entire negative post group. I've flat towed it about 6,000 miles with no problems. Need to add tail/brake lights now.
Green Mtn Boy, please add the pics of your install.

For what it's worth, I added the extra light bulb in each lens for the rear lights when towing. Adding the bulb involves drilling through the plastic lens and inserting an extra bulb socket. This eliminates having to tap into the wiring on the car leaving all the lighting wires in tact. Worked very well and was easy to do. I decided to put the car on a dolly rather than flat tow it. Read some horror stories about blown out trannies while flat towing.
If anyone want to see pics of this lighting set up, let me know.

Disconnecting either positive or negative will accomplish the exact same thing.
You always disconnect the negative first for this simple reason:
You might accidently touch the wrench to chassis ground and complete an un-fused 1000+ amp circuit if you disconnect the positive first.

disconnecting the negative technically works better since the theory is that electricity actually flows from negative to positive. Although I'm sure you've heard that before if you're an engineer. That's what I've done for years with all auto electrical (i'm an installer). If it's hard to get to and this is something you plan to do regularly I would pretty much do what you were thinking for the positive, but on the ground side. only have to take it off once and put a quick disconnect on it with a larger gauge section from that back to the battery. might even do the big three while you're at it.
part of the reason for doing ground instead of positive is that some component will still hold a charge for a while after battery is unhooked, taking away the ground not makes it impossible for anything to short out.

|cbABQ||I'm going to tow my Focus behind my motorhome too, and I plan on disconnecting the positive battery post with a knife switch. I'm an electrical engineer and it makes since to me that removing the positive connection should accomplish the same thing. But i will admit that I'm not an automotive engineer. i did see another guy this setup tho.|
