A friend has a new 2011 F-350 and wishes to install a heavy duty charging system for his 5er. On my 7.3 I tapped off of the glow plug relay for a source to close a constant duty solenoid to charge the battery only when the key is on. Where on the 6.7 is the glow plug relay or another key on source for 12 volts?

Thanks,

I believe there is no longer a glow plug "relay", but rather a Glow Pug Control Module.

He should be able to find a "keyed" source at the under hood fuse box.
