That is kind of funny. I was wondering how many beers you had had tonight <img src="/forums/images/graemlins/cheers.gif" alt="" />

When you say 'control' box, are you talking about what the manual calls the "diesel engine control module"--originally mounted inside the cab under the dash on the driver's side, or the two glowplug relay boxes (located originally in the engine compartment near the battery)? It'd be nice to know if that "diesel engine control module" is really truly needed or not. Electronics in engines is not my strong suit.....

For computer protection, I can highly recommend Kerio personal firewall ( http://www.kerio.com/kpf_home.html ) There's a free version available for home use. But that's kind of off topic, send me a PM for help with that.
