Well thats a new approach cutting off the terminal blocks and rejoining them through another connector, is it only me that can see the problems that could cause, there is a fault there as otherwise the light would not be on maybe your electrian cant retreive the faults that he needed to also most srs conections now are made of gold to reduce resistance levels at the connector, also some srs components can have residule voltage in them to still be set off after 20 mins, also a 9 volt battery in a multi meter can set off an srs component so be affraid, most srs cables and connectors are yellow in colour and wires are twisted.
