Bought prematurely off EBay to cure my SRS light. However, the fault turned out to be the rotary coupling and this was not required. To check function, once I had the fault cured I connected this air bag and the SRS light went out correctly. So as far as can be told without setting it off, it is fully functional. The outer surface is in excellent condition, better than most on EBay, with a green LR logo.
Asking slightly less than I paid at £20. I would prefer not to post given that this is potentially dangerous, but will arrange if required for £5 .
