I thought I would post this as I am up fitting/improving on the Sportsmobile build I am doing currently which includes the new Espar D2L and Pro Controller. This controller has a built in high altitude switch and much less wiring compared to the older controller. You do however have to tell it to "switch" to high altitude when started. The controller however has built in diagnostic and the fan on the heater has higher use life. The other parts of the installation are pretty straight forward like the other models; (fuel, power). Its basically 4 wires/pins and a resistor (they ship with) you deal with outside of the power and fuel. The pump as well is quieter. The installs for these heaters are more than covered enough on the web with many examples so that won't be covered in this thread.

This thread has already been so helpful, thanks for the wiring diagram, I wouldn't have figured out that you needed to move that resistor.
Wondering if you can help me figure out the power situation on my wiring harness though. I have the new Espar S2 D2L but my wiring harness looks a little different than every tutorial / video I've seen online so far - even ones for the S2 D2L
It also seems different than the wiring diagram in the manual but I'm not super familiar with reading electrical diagrams.
This is the whole wiring harness:
I'm confused about the power situation because all installs I've seen have had a large red (20a fuse), large black, and a small red wire (5a fuse). But this harness has two groupings of long wires: (1) ends in a large red and large brown
- it would seem these would be the positive and negative and fuse red with 20a? and (2) a grouping of yellow, redwhite, bluewhite, brownwhite, greyred, and red (is this the small red wire that's in everyone's install videos??)
.
What's throwing me off is this 3a fuse block coming from the main harness
Any help would be super appreciated. I'm assuming that this is the "simplified wiring harness" discussed and maybe I'm overcomplicating things. FYI it did also come with an inline fuse with 15a and 20a fuses.
Is this what your S2 D2L harness looked like?
