bluecoup, I learned about the block heater from Dave just after I got my 08 Roadster a couple years back.
I found the heater, just didn't have a clue what it was.
Better with a wrench than a computer so hopefully doing this right by attaching a link to earlier post, https://www.crossfireforum.org/forum...ification.html

The roadster is stored away heated all winter so would never want to give them the crazy price they wanted for the cable.
