2008 Ford F-350, Omega RS-4LX Remote Start

I can't find this info. anywhere.  I need to find the glow plug wire to tap into for my remote start.  I have searched and searched, called Ford, posted on other forums.  So far nothing.  So does someone know the wire color and where I can find it?  If it's easily accessible under the dash thats fine.  If I can find it under the hood, just as good.

Thanks for the help.

No the RS is not programmable.  It has a sensing wire that senses when the glow plug light goes off.  I know that it's under there somewhere it's just a matter of finding it.  Going through that monstrosity of a harness would take me all day.  I am sure there is someone here who has done this truck before that would be able to at the very least, narrow it down for me.  Someone must have a wiring diagram that they could reference.  Thanks.

All you're  looking for is a delay between ign and start. Most good R/S units can differentiate, ie selecting diesel on the programming will initiate this inc the time delay. Frankly most modern diesels DO start straight away so waiting for the glow-plug light to go out is irrevalent (where's the bloody spell check?)

In fact all the above posts are correct although they arrive by different methods ALSO from experience I would also trust in what they say. In fact on modern diesels I usually leave them on their petrol settings. My only doubt is the depth of winter, does the glow plug need more time?

Thanks for the help guys.  The unit I am installing is an Omega RS-4LX.  I have installed three of these before but never on a diesel.  I don't want the truck to start before the glow plugs warm up.  I don't care what you say, it's not good for it.  In the dead of winter it can take 5-7 seconds for the glow plugs to warm up.  I don't think there is that much delay in the ignition and start sequence.  So I appreciate the idea of just hooking it up but I don't like it. 

Ckeeler, So it sounds like I would need this DEI 528T timer your talking about.  How does it work?  I'm not doubting you on the data wire.  But for the dash light there must be a wire that gives the light voltage and then turns the voltage off, turning the light off.  That would not be a data wire.  Thats all I need.

Mikvot, when I posted before I was asking a question about my keyless install and the lock unlock wires on my F350.  Since this was a "different" install and a different issue I thought it better to post a new topic.  I figured I would get more direct responses.  Anyway like I mentioned above the RS unit is a RS-4LX.  I love these things and their features.  BUT.  The diesel feature does not have any programmable wait to start option.  All I have is a sensing wire to sense when the light goes off.  I figured I would not need the tach wire as all the other installs I have done, all Fords, didn't need it as they worked off the voltage sensing system. 

Thanks again guys.
