Volvo v60 manual seats to electric seats retrofit help

[tahakxrd]

For the heated seats, you will definitely need 2 wiring at least  (Power and LIN).  For ground, it depends on your current ground ground wire thickness. 
For the full electric, it might just work but it'd would be wiser to double check the wiring diagram which I shared in another thread. 
If your new seats, has side support too, then you will need another positive wire, Side support  is part of the massage seats module regales the seats have massage option or not.

So in quite new to retrofitting and reading the diagrams. I took my old seat out and looked at the wiring I don’t have any additional wiring in my chair unfortunately. I took photos of my pin but I don’t know where to go from there I haven’t purchased the seats yet until I’m certain I can do it. For the power do I need to feed a completely new line from my seat to the fuse box so it’s “oem wiring or am I hot wiring a power cable else where to the seat.
