I did the deed yesterday...hooked it up like that wiring diagram...the wait to start light works as it should...the relay clicks once as it should...apparently the glow plugs arent heating up...the volt gauge dont go down at all and the interior light dont get dimmer and it cranks like crazy when i go to start it. I dont have time today to deal with it. I got other stuff to get ready for the work i gotta do this week and my daughter just went into labor early this morning. gonna be a pappy again sometime today or tomorow morning depending how this one comes out
