Hello community,
i just noticed that there is a difference between my old D1005 stop solenoid and a newer version.
The old one just had one connection and ground to shut of the fuel rack.
It seems that the newer ones need to be engaged to allow fuel to flow.
They also have two connectors.
Can anyone enlighten me on these? and how to connect them properly?
thanks!
