Onan has their own system, the energy command. I should, but I dont remember what was on my Blue Bird... only owned it 8 years
. It had a Kabota 15kw genny! There are several different systems that require alterations in wiring as you know. Example, if ac not available will start, or dc volts to low will activate auto start. It all depends on what you want. I dont remember if i had a remote? I did have a panel that allowed me to set the parameters if that's what you mean..
