Adding Rear mounted CC fuel tank, sort of...

All trucks come with plow prep wiring…
I made my own PDC for my plow lighting cost me 50$ instead of the 2500$ Fisher wanted for just the electrical

So you have the AUX PDC also?

Yup i have the aux switches, if i didnt i would have put my plow PDC in the spot where the AUX PDC should be

All CTD equipped 2019+ come with the aux PDC because the PTC cabin heater uses those three relays/fuses.

i need to add those, but for now Ill focus on getting this tank wired and setup correct.

Makes sense… i didnt know we had one, is it for heat before the engine warms up?

Yes

 

[H3LZSN1P3R]

Yes

Awesome, i did notice the cab warmed up much faster than it should, i thought they may have one but never looked in to it

my Daily driver, a 2000 VW TDI manual, warms up about 15 minutes into my 20 minute commute but it gets almost 70mpg.

so... should I install a fuel heater for my aux tank? nah, I live in the south and not planning on winter camping up north...

Didn't think so... Just saw circuits to activate

 

[Jimmy07]

Those circuits are already active on all CTD Rams. They all have two fuel heaters active regardless of tanks or chassis configuration. One is for the rear fuel filter, and one is for the front filter in the engine bay.

So... a small update, still working on the project, installed fuel sender in my aux tank, waiting on fuel pump, filters, water separator, and connectors needed for the wiring.

Awesome also pictures would be great to make this a DIY thread

Will do!

Will do!

Thanks

Yes I would love to see some pics as well. Pretty cool idea

 

[stinson87]

I am going to delay some of the final install until my CP4 recall is complete. I am gathering pictures of the setup, parts I added, and wiring and pins when complete, or close enough to run alfaobd testing.

 

[stinson87]

Here are a few pictures of the current setup. This has the fuel level sender and the rollover vent valve installed. The unistrut is going to hold cover plates that hides all of the connections.

@stinson87 Apologies for digging up an old thread, but did you ever finish this? I am adding the factory midship tank and everything is working except the actual fuel transfer. So far I have not found a wiring problem so I am starting to wonder if AlfaOBD is enabling the Pin A16 setting properly..
