Thanks guys your really helpful.

I traced the wires through to the srs ecu and have found the passenger airbag connector. Unfortunately I don't have a multimeterto test the ressistor but ill be able to borrow one on Monday.

I have reset the srs a few times and have no issues there to do it again once I work out the ressistor issue.

Does anyone know where I can get a replacement resistor from though ?

Thanks for all your help with this guys
