So I purchased some leather seats and just finished giving them a full rejuvenation with a combination of leatherique and duragloss.

I went to fit them today and found that the yellow plug (airbag?) doesn't fit the one in the chair...
Also I have a green plug (heated seats??) that I want to utilise so I'm gonna get something like this Genuine VW Golf Bora Passat Heated Seats Looms With Switches Seat Heating | eBay

Can anyone tell my why these two don't match up? I read something about old and new gen changing plugs, if so, how do I make this work? Mine is a 2004 so will be new gen, which makes the bora seats old gen.

After spending around $100 bringing these seats back to near new condition, really don't want to give up on them, but I also don't want to **** up my airbag...

Also noticed the bora seats don't have the baby seat harness on the back of chair as I read these are attached to parcel shelf obviously, is this a legal requirement? Will I need to hold onto my seats and switch back when it's time to sell?

Thanks
