outback install?

I need to install a system in my friends 2015 Subaru outback. Has anyone tried to install the rear sensors? Are the extension cables made for the type sensors? I bought the system last fall before the price increase. He is just getting the car now. He will be driving up to NY from Florida in a month for me to do the install.

Couple of things:
1. You'll have to confirm w/ BRD your(his) cable connectors for extensions are compatible w/ current ones.
2. You may not need extensions if you place the Control Box midships (behind Driver seat ?) to take advantage of full lengths of each for Front & Rear runs.

We stock all old and new parts. You just need to verify if you have the new Twist & Lock connectors or the old Din Connectors. We keep both on hand.
