Default under seat airbag connectors

I have had an intermittent airbag light. I think it is the connector under the passenger seat. I unplugged and cleaned the connector a while ago and it cured it for a few months, but has now come back again intermittently. More wiggling, cleaning etc, and now the light is on all the time!
So I think it is time to go the replace the connector route. I don't really want to permanently solder the wires, so would prefer to replace with some other sort of connector.

So ... wondering what types of connectors people have used successfully?

thanks.

Hi David.
These are a good alternative to the original ones, if you are going to change them over.

Used successfully at a few Nano meets, i made these up myself but you can order them already made.

If the OEM connectors haven't otherwise been damaged the problem is an easy fix. The (usually) intermittant signal is due to the plug assembly being 'stretched' thro' the mobile nature of the seat geometry creating a minute make/break condition (termed 'fretting') and has a lot to do with the SRS wire routing - the AMP plugs are otherwise fine.
Search for MG Rover Group Technical Bulletin TB0133 that explains everything in detail (whilst your at it also take a look at TB0015 and TB0029 covering related issues)

I had the damn airbag light trouble, it took ages to sort out, and at the moment I have just some simple spade terminals looking after the issue for me.
I can confirm the terminals Artic has posted a picture of are well made and should of done the job for me.
I used them, and went to the trouble of soldering the wires in rather than just crimping them, but unfortunately the problem was further down the line, and I had a break in the wiring.
I have every intention of replacing the spade terminals with the above shown plug connectors.
They do give have the profesional feel to them which standard spades or bullets dont.

So, is the big airbag warning supposed to come on the IPK for a few seconds after starting, and then go out. or does this indicate a problem?

As far as I know it remains illuminated.
There have been more than a few reports on here of 'new' owners discovering the that the IPK lamp aperture has been blanked-off (bit of insulation tape on the inside of the display) to block out the illuminated lamp because previous owners have not (been able to) resolved the warning light issue.
