[Discovery 1 srs light]

I have a 1994 Discovery 1 v8 and the srs light is flashing, it is now out if mot and will fail with the light on.

It is the very early system with two crash sensors, I have checked every connector and replaced the clockspring to no avail. 

I am trying to find someone who can plug something in to the srs snd reset it or read any faults, it is a pre obd2 system so gas no obd plug just a four pin connector. 

Rovercom sell a lead so their system would talk to the srs, does anyone know of anyone who could do this for me.
