I am going to install a viper 5701 in in my 2007 f250 6.0l diesel and was wondering if anyone could give me some insight. Will I need any diodes? Do I really need an interface? I've never installed an alarm but am very mechanically and electrically inclined. Just need to hear if there is anything special or not that I need. Thanks a million
Only thing that you will need to pay attention to on this vehicle is the wait to start ( use timer module or if 5701 has one builtin, set for 8-10 seconds depending on your climate ) and also the tach signal ( use BLUE wire under dash on driver's side ) but set unit for low threshhold signal. No need for a module on these SD's

Larson0290,
I am just about wrapped up on installing a Viper 5901 into a 2006 F250 diesel that has a remote keyless entry and I would bet that the similarities between the 07 and 06 F250 are few. A couple of lessons that I learned:
I originally wired the alarm into the individual door triggers (its a 4-door SuperCab) and used diodes so that the Vehicle Security Module would not get a signal on the driver's door when the passenger door was opened (as an example). The problem I ran into, though, is that the vehicle indicates 12v on the door ajar wire when a door is opened, but only for about 5 seconds and then it goes back to 0. Same thing happens when you close the door. The alarm kept thinking that a door was open and I needed to reprogram one of the menu options, which requires you to open a door and follow a few steps to get it into programming mode. Well, after those 5 seconds elapsed, the alarm sees 0 volts on the door ajar wire and exits the programming menu. Frustrating. I followed just about every other installers advice and simply wired the door ajar trigger to the dome wire. All works fine now.
Presently I am using two external relays. One to provide power to the dome light when the alarm is disarmed and the other to wake up the GEM. I have a document that I pulled from this website that shows how to wire that relay.
I have spent hours combing through numerous posts on this forum to get the answers I needed and my installation went very well. Even with the Viper installation manual, it was a bit difficult to understand how some of the features work and so I understand the frustration you may be experiencing. I also have the complete Ford factory service manual with complete wiring diagrams and such, which is a big bonus. I'd be happy to help you out and send a few electronic documents that I have saved. Feel free to send me a private message and I can give you my direct e-mail address and phone number for direct correspondence.
Good luck.
David

Uh... I meant to say that the differences between our vehicles are few. Clarify for me if your 07 F250 has remote keyless entry.

thanks for the help guys, I have still yet to tackle this. Yes my truck has keyless entry. And it is only an extended cab not a crew cab if it matters.
I would not think that extended vs crew cab would matter. Does the extended cab have rear doors to accomodate the rear bench seat? If so, do they have individual door triggers? Either way, I would encourage use of dome supervision in place of individual door triggers.
