Long time lurker, first time poster so Hello to everybody.
Does anybody know what the part number specific digits stand for on an SRS unit? I've checked Honda UK catalogue and I know I need a part number 77960-SAA-E81. However when I check ebay all available units there have a longer number, i.e: 77960-SAA-E812-M1.
Would you know what the additional numbers stand for and if they are essentially the same units? Or, do the numbers need to match precisely?
Thank you very much.
