Mounting light weight battery & e start any advice?

Hi;

About to take my old 08 e start that I had put on my 2012 and install on my new 2013 XM. I see light weight Shoria battery will sit in different, was hoping to use same starter relay module. Notice from parts fish it's different for 13. I don't see a second plug in relay under dash like last years to install. Looks like no wire to cut near battery ether this year.... Expecting to use new wire harness to control starter solinode relay.... Starter and bendixs looks the same... Any heads up would be great.......

Thanks for reading.

Hi;
I had this battery for the last season in my 2012 E-tec engine, I think same as yours. It worked fine in all temperatures up to minus 10 or more. Cranking for e-tec engine much more then for a Rev engine for sure. The one thing about these light wight batteries is that if not used every day that you must introduce a draw to them to activate the electrons and revive. I use to allow my head lights to run for up to 20 seconds and then you would get get proper performance. So far so good for me, will report after second season....
