Not familiar with these cigarette type plugs. On my motorcycle, I had to wire the Battery Tender Jr. and heated gear coax directly to the battery terminals. I've looked at threads and know the battery on the SS isn't easy to get to.
Can that back center port be used for these things? All I would need then is an adapter. That would save me a lot of wiring time if so. I searched through threads and only found that that plus is always on and the glove compartment one is not.
Thanks for any info............
