Ford Windstar EVAP Canister

Can anyone tell me where the EVAP canister purge solenoid is located on a 1999 Ford Windstar with the 3.8 engine?? I replaced the vent valve that is located on the canister itself but cannot locate the purge solenoid valve. Any help will be greatly appreciated.

It’s mounted on the firewall, next to the EGR valve.

Thanks. Found it. Kind of hard to reach and had to change it using only one hand but got it done.
