I posted this on another forum, so for some, this will look familiar.
I installed the Cummins Onan EC-30W wireless auto generator start this weekend. It's an easy installation, but, when I have time (ha!), I'll need to make some wiring changes.
I do some dry camping at some car shows where it gets pretty hot. This will prevent me from having to run the generator all the time.
Pictures are below. You have to buy the appropriate wiring harness in addition to the EC-30W. The wiring harness is essentially a splitter so that both the switch on the dash and the EC-30W module can be connected to the generator.
Unplug the harness near the front of the generator and plug in the new harness to the existing harness on the generator side. Plug the dash switch end into the new harness and plug in the EC-30W.
Next run the purple wire to the back of the generator. There's a 12v+ terminal (next to a ground terminal). Connect the purple wire to this terminal to supply power.
Finally, mount the EC-30W somewhere. I used double-sided tape to attach it to the firewall. To be safe, I also used 2 short sheet metal screws. I was worried I might hit something with a screw.
I only had a chance to check if it would start the generator manually. I'll check programming it when it gets warm enough.
