LPG monitor in coach

[Ron Keelen]

Have acquired 1999 Lxi and in the process of replacing and repairing neglected items and systems. Working on LPG, currently not getting gas to coach (tank is 3/4 full). Checked main switch next to tank, open. Purchased replacement Safe-T-Alert for gas and C0 which includes new solenoid valve. Think solenoid valve is closed. Wires that were attached to old monitor on base of kitchen cabinet are white, green with white strip, purple and green (4). Looks like previous owner had connected the white and green(with white stripe) together for some reason. My alert monitor has two white, one black and one red wires. Has anyone replaced their Safe-T-Alert monitor and valve that could give me some advice as to the correct wire connections to make.
