How do i find a wiring schematic for a 1980 Hillcrest mobile home? This is not aRV.
I am not sure if this is what you have done sofar....
but i went to the skylinecorp.com website , and found a tab to get resources.
click on contact Skyline, and below on the page is a place to request literature.
They also have a number you can call and talk to them, they might be able to send you the information directly(NNN) NNN-NNNN/p>
If this is what you have done, then im just repeating your efforts. But let me know and we might be able to dig deeper to find you some wiring diagrams for your place.
