Does anyone know anyone whose had either of the following "add-ons" for a FEH or MMH?

1) A remote starter? I'm guessing it's probably not a good idea to mess with the electrical system by adding security systems / remote electric starters, etc but I'm curious to know if anyone else has done anything like this.

2) A side mirror blinker add-on for a FEH or MMH.

I just put in an order for a MMH and it's really really cold where I live.

Thanks in advance!
