Installing an Espar D2L with an AUX battery under the passenger seat

Mostly the mounting bracket for the heater. It works well and has good airflow. But it turned out to be overly complex. I thought I needed it but after I built a the battery bracket I think there is enough room to just mount the heater on the floor.

Basically it’s over engineered. In the end though I did only drill 3 holes, and their positions were a little less sensitive to errors. So there were fewer opportunities to really screw up.
Hey! I'm getting into a 2020 144 soon and it's more than likely going to come with the auxiliary battery under the seat so this has been super helpful! Do you happen to have any more pictures/measurements for that wood/metal tray you made? Hoping to do the same thing with the heater and battery under the seat.

Sorry I don’t. I used 3/4” ply and 1” Al angle. Don’t worry about measurements. Just make a cardboard template make it as big as you can leaving a 1/2-3/4” boarder open to run wires in. It was quite easy and I’m happy with how it came out.

Hey guys. Hoping for some help here. Just got my espar d2 s2 sprinter kit from espar of Michigan and I have some questions regarding the harnesses if anyone has ordered the same kit. My question is in regards to connecting the supplied easystart pro extension harness pictured

To the other harness provided:

I've identified the heater connector (big one left top), fuel pump (green wires), and diagnostics port, (black connector on bottom). My question is if the loose wires in the 1st harness get terminated in this female supplied Deutsche connector:

Then attached to the grey Deutsche connector in the 2nd picture that is capped with another connecting wire, then this cap with connecting wire is used on the extended easy pro harness male grey Deutsche to complete what I'm assuming is another diagnostics circuit.

Sorry if this is confusing. I am a bit as well haha

Also, just confirming....I believe this loose set of 6 wires included in the harness is for wiring included in case one wants to use the wireless features associated with the app and is not used for just the basic install correct? 20201223_213121.jpg

I don't think it will fit along with the aux battery. My 2019 came with an aux battery under the passenger seat, and I had to remove it. The metal plate needs to be sealed near airtight. Along with the foam included in the kit, you could add some of your own if you install it an a very uneven area. It is bad practice to allow any exhaust fumes easy entry back into the van, in case you have leaks in the future.
Where did you move your oem underseat aux battery? Im have one too and would like to put an espar under the passenger seat. Am I better off just putting the espar somewher else?

Finally got it done. I ended up building a bracket to relocate the stock battery.

worked like a charm. It’s reinforced on the bottom by aluminum flat bar.

The battery is rock solid with plenty of air flow. View attachment 155769

The wiring of the easy start pro is trivial. Just plug in the 4 wire connector. I located the unit just behind the slide for easy access.

Heating vent came out pretty easy too.

I’m a little surprised by how loud it is outside. Not bad inside.

I did smell some melting plastic. I’m not sure if It’s just a new heater breaking in? Or maybe some wire too close to the exhaust. I’ll wrap the exhaust in ceramic insulation and aluminum tape and all will be good.
Did you use stock holes to mount your wooden battety plate?

Yes. If I’d wanted to drill new holes I think I could have just bolted a plastic battery bracket to the metal floor. I didn’t like the idea of extra holes so I used the stock ones. What you can’t see on my plywood bracket are aluminum flat bar reinforcement. I think
It may not be needed but I had the stock laying around.

The old saying a picture is worth a thousand words, still remains true.
Ray at Espar Parts sent this picture to hep on our install.
Hope it helps :)

Does the fuse in the middle of the picture that isn't labeled require a 3 or 5amp fuse? I believe mine came with a 3 amp already installed but wasn't sure as I recall another install video showing a 5 amp fuse there. Cheers

Did you relocate your stock Aux battery, or just remove it? I have battery under passenger seat and would like to install an espar D2

On page 2 of this thread a member detailed putting the espar d2 sl2 under the passenger seat with a stock auxiliary battery. I plan on doing the same
