As promised, now reporting back after having a go this morning, and failing.
Everything going swimmingly until refitting the squib. At about the 1 o'clock position there's a long connection that goes further back than anything else and a yellow plug connects into it.
I didn't disconnect it when disassembling, but I figure now it MUST have been!!!
When connecting these when squab is not in place there is a very definite hard click when in place and to disconnect, I need to pull the white tab underneath. I deffo didn't do this when taking apart.
The trouble is, the yellow plug doesn't fit in the opening at the rear of the light stalk, either with the squab off or on so I convinced myself it couldn't have been plugged in before and reassembled without it.
With the squib in place
, the yellow plug will not come forward enough (comes against the rear of light stalk) to click properly.
So, I put everything back with that disconnected, and as I feared, I now have an airbag alarm!
I can only assume it was in place before but not clicked in as far as it should. I know..... it doesn't make any sense to me either, but that's the only thing I can think of and will have to have another go on Thursday - my next day off work.
I took photo's, not sure if they will mean anything, but if anybody has any idea, I'd be very grateful.
The last one (close up), shows the size of the plug and the size of the opening it need to fit to enable it to click into place.
