I'll have to take a picture of it. I'm not sure how it is wired up, but it's a GP gauge with an on/off switch. Not sure how it even works with the standard GP system. I'll have to ask one of the mechanics on friday about it. I'll take a picture of it then.

 

I have used a momentary switch for over three years now and am still satisfied with the way it works for me. Most of the time I just hold the switch on for about 30 seconds on my first start up, then after its warmed up good i don't use it. ( I don't drive my truck very often and much less in the winter )
I don't know about the concerns some have about carbon build up on the GPs, I thought the reason we use the beru's motorcraft gp's was so we wouldn't have a build up or swollen tips that make them difficult to remove.
Here is a sequence of 4 videos on a very cold start up on the morning of new years eve, it was very cold burrr about 5 degrees. Just thinking some of you may find this interesting or at least amusing.

I have been wondering about dieselRX's. I used those in my audi 2.5 when I was in Germany, and even on the coldest of days, it would start right up!

 

Rosewood diesel sells DieselRX glow plugs. Jim says they're good stuff, I've just never tried them (yet).

 

Links are working now! That's a nice setup you have there! I could see how a triple post would come in handy, instead of holding on the switch the whole time. I've seen lighted ones that glow when they are on, or maybe rig it up so you have a LED light on when you are in manual mode.

EDIT: What is the hose by your stick there in video 3? And nice Galaxy(?) setup location by the way!
I don't see many posts on the DRX GP's, since pretty much everyone here swears by the motorcraft god plugs.

 

Carbon build up has Nothing to do with the brand of plus. It has to do with the glow plug Not working.

Swollen tips is when other brands are used

 

DZLJim has a good, well thought out system mod on his projects page at Rosewood Diesel Shop. He uses a temp sensor in the water pump plug to disable the GP's through the GPR when the engine is warm, a relay from the start switch to disable the GP's while the engine is actually cranking to reduce the load, and a switch in the cab to disable the GP's. Leaving the system in normal allows normal cycling of the GP's at least for the first start of the day and anytime the engine has cooled down, unless the disabling switch (for Jose's climate) has been turned on.

 

I switched from naw4 pcm to tde0. Now when my engine has some heat in it my GPS don't come on. Its all just programming. Too bad a tuner couldn't program the disable into the chip depending on temp like OE did on some.

 

I bet one of the chip programmers could do just that, provided you asked nicely and offered enough money.

 

For anyone interested in DZLJim's mod, I have been unable to find the water pump sensor anywhere. They are out of production and NAPA did a nationwide search...couldn't find any. I have a radiator sensor used for electric fans I may try to use to control the relay.
