Tom, I was cleaning up my reply when you posted.  You are correct in that the socket at the tow vehicle needs to mate with the coily cable you buy.  So if replacing the coily cable, get the mating socket too.

There are at least two flavors of coily cables.  All have the same style connector by the PC that looks like this.  (note that this example has only 4 metal terminals)


The difference is at the other end by the tow vehicle having 4, 6, or 7 terminals.  If you have 6 or 7 terminals, then 12V from the PC is right there where you need it.  You'll only have to run a wire a few feet from that connector on your tow vehicle through the rectangular 2 terminal diode, then to your tow vehicle battery.  It is a very easy modification for someone who knows what they are doing.

This is the end of a 6 terminal coily cable.  You need at least this many terminals.  If you have this you are in great shape.


Here is a 4 terminal coily cable end.  If you have this one, you'll need to replace it and the socket at the tow vehicle.

Another approach might be to add a charging line from our coach back to the Honda battery, but that seems to be much more difficult.  Any ideas?  Bruce
I believe it is quite easy to wire the tow vehicle into the PC 12V system for battery maintenance.  Power from the PC to the tow vehicle battery is run directly through the main red coily cable in my picture, which includes brake, tail, and turn signal lighting.


My Unified tow brake system diagram HERE does exactly as you describe.  I would follow the diagram 12V battery portion alone.  Just ignore the majority of the wiring diagram.  It should be extremely simple.  I believe the 2 terminal box is a diode, but I would need to confirm that.  You'll need only one (assumed diode) in the tow vehicle.  The other in the motor home is not needed because the PC is pre-wired, ready to tap 12V power at the connector in back.

Here is the diagram of the PC connector, an industry standard connector.
Terminal #4 would be the one to use for tow vehicle battery maintenance.


Here is an example of my wire harness.  One end mates into the PC, the other with round terminals, plugs into the tow vehicle.

It is seamless, very easy once setup properly.

The manual had an email address for questions but it bounced back today.

Thanks for the phone numbers.  I will try them Monday.

.....but with the number of times I hit my head on it......
Oh yes indeed.  That is why I moved it here.  If you look close, you can see where it used to be on the headliner.  One day I'd like to mount a low profile cubby for little things to store and to cover up that hole.

My ZD manual is too basic.  It doesn't offer anything of value.  The book says it's System 322.  It implies the microphone is in the camera but I can't find it in that little thing.

The only light is saying service engine soon.  Spoke with Ford dealer in Bristol, and he said it could be a number of things and can  not see us until Tuesday to a diagnoxtic test.
Oh, Okay!  So your "Service Engine Soon" light is on.  The problem is likely unrelated to the transmission or the tow/haul mode, but might be simply influenced by them.  A Ford dealer should be able to identify the problem quickly.

Our 2007 2350 was equipped with a Zone Defense backup camera system which also included sound in the back of the rig.  A few years ago my sound dropped off.  Since the monitor can still raise the volume generating the loud hissing sound from over-volume, I assume my microphone is still working, but might be blocked with a spider nest or other dirt.  My problem is that I can't find the microphone.  I inspected the camera very closely for even a tiny pin hole for a mic but nothing is there.  I looked elsewhere in back of the rig but found nothing.

Does anyone know where the microphone is located?

My daughter is already pushing for a 2910T to drive to competitions around the state and country.  As I'm just in my 30's, and a single self-employed mom, it's probably going to be awhile before I bring home a PC.
  Just say the word (and your spending budget) Aimee and we'll find something affordable.  Likely not a 2910T, but something that will work well for you and your daughter.  Most women who go solo with a pet or child prefer a short rig.

Then again, just tell that info to Earl, and he'll take best care of you.  But you already know that.

Kermit told us that when you have the tow-haul switch on, you can tap the brake on a descent and the truck will downshift into a lower gear. Tap it again and it downshifts again.
I believe our 2007 Torqushift transmission with tow/haul mode is the same as installed in the 2013s.  I never knew this.  Under such conditions, I've always braked aggressively until the rig slowed down enough to down shift on it's own.  I'll have to try that tapping method and see if it works for me.  It would be great if it does.

If you are still within the 3 year/36,000 mile Ford chassis warranty, I would definitely get that rig over to a Ford dealership and have them check it over.  Even if they don't find a problem, you will be in their system.  If it later becomes a big problem, you should be covered because the initial complaint happened during the warranty period.  Vehicle manufactures are pretty good about that these days....especially Ford.

Hi Steve,

PC-USA does not change out the Ford shocks unless requested by the customer.

I am not sure about the 2012 E350 chassis, but the 2007 E350 chassis we own, the original Ford shocks were considered "heavy duty", but were inferior compared to Bilteins-RV and Koni-RV.  I compared 2007 specs and the E350 cut-aways were equiped with the exact same shocks Ford installed on their E250 van.  So take that bit of information for what it's worth.

Our 2007 E350 2350 has Koni-RV adjustable shocks that we had installed as part of an over-all suspension upgrade, done after we took delivery from PC-USA.  Because so much changed all at once, I can't compare just the shocks, only the over-all change which was miraculous.  Our shocks are set to stiffest for best handling so the ride is not as cushy as could be.  I never tried them set to soft because changing the setting involves dismounting them.

I would hold off on new shocks only because Koni is coming out this year with their best motor home shock called FSD.  They change as conditions change, soft when they can be for a smooth ride, and hard when they need to go into heavy-duty mode.  It happens internally within the shocks, occurs instantaneously.  FSD shocks have been available for class A motor homes for many years.  They are finally coming out with ones for the E350/E450.  I would wait for them.
1633  Main Forum / General Discussion / Re: Tank heater(s) -- 2008, 2900 PC on: October 10, 2013, 12:43:44 pm
This applies to all PCs with tank heaters.  They heat just the gray and black water tanks, nothing else.  The 12v heating pads are bonded to the underside of the two tanks.  Then the tanks get wrapped in a foil-looking insulation.  You won't be able to see the heating pads.

The rest of the motor home plumbing & fresh water tank is inside the insulated rig.  As long as the interior is kept warm, nothing should freeze.  But there are limits.  I would imagine that you'll have trouble under subzero conditions.

I think the most vulnerable things freezing are the dump valves, based on stories read on RV forums.  The tank heaters will radiate warmth only so far down the pipes.

I traced the wiring and drew them up.
You are a very determined and thorough PC owner.  Anyone with your model and year (2012 2552) would surely benefit from your efforts.

I would assume wiring will vary pending model and year.  I believe my 2007 2350 is different than one made a few years later, given some things were dramatically relocated, for example the furnace moving from the driver side to the passenger side of the rig.  I also assume that a rig with a slideout will be different than one without.  But then again, schematically speaking there might not be any difference.

I have been to the factory four times, twice for each PC. First was to see it being built and the second to pick it up. Now my DW will not let me close to there again.Cry
Tom, You are so funny.

It's a good thing you live many miles from the factory or you'd have first-hand experience with every model.  Smile
