I have a Compustar 2WFM-AS alarm I am putting in a F-350 Diesel. I have yet to find the tach & glow plug wire in the truck. I'm not sure if I really need the glow plug wire, since I do live in a warm climate all year, but good to know for future reference.

*1 Without keyless entry use pink / YELLOW for lock and pink/lt. green for unlock. They are 5 wire reverse polarity mastered from the driver switch and found in either kick panel. With keyless entry use WHITE/ red for lock and BLACK/ white for unlock. They are negative trigger and found at the VSM. On the vehicles with keyless entry the GEM shuts down after the doors have been locked for a certain time period, to 'wake-up' the system refer to directfax document #1094. *2 The VSM (Vehicle Security Module) is to the right of the accelerator pedal above the transmission hump below the radio. Not accessible from radio opening. *3 For tach go to any one of the ignition coils and use the wire that is NOT RED / lt. green. On diesel vehicles the tach wire is green or white, in a 42 pin plug under the clamp on the engine side of the air intake duct. On diesel vehicles the wait to start light is activated by a databus wire from the ECM. To do wait to start use a pulse timer relay and follow directfax document #1091. *4 Also found at the radio on vehicles that have the in-dash CD changer. Is up to the installer totest all wire whenever pssible with a DMM ------------- Luis

You should still use the glow wire just because of two reasons: Starting the truck when the glow plugs are activated can be a huge strain on the batteries. Do you ever travel? Wouldn't it be nice to be able to start your truck in cold weather too?

Easier place to find tach.................. on the left side of the steering column, there is a big bundle of wires. Taped to the OUTSIDE of this bundle is four wires that stubb out, taped at the end from the factory. Use the GRN/WHT wire for tach. I did an 03 a few weeks ago, works perfect, and in an easy place to get to. ------------- Hak

Actually, that is not true. I have yet to see one that is databus. Unless the canadian version is different then the U.S. Either way, there is more then 1 way to skin a cat. Option 1 - BLACK/ pink behind instrument cluster Option 2 - White at the Glow plug relay that is located on the left side of the engine. You can use the white wire + or the WHITE/ green wire coming out of the relay or at the pcm module (left side of firewall) at pin 8 + while wait to start.

And Haku is right about the tach! That is the only way to go!

I dont think that US/Canadian are different. From my info, 03 and up are databus on the wait to start. The 03 I just did was databus, but 15 sec timer works just fine.

Haku, did you actually test that 03? My company truck is an '03 and i was able to get it at the intrument cluster. I have done about 5 or 6 03's and have yet to find one that this didn't work.
Was the one you worked on a 7.3L? Perhaps this changed when they changed the engine. The instument cluster is the same part number according to my local ford dealership so I don't see how anything changed.

It was the new 6.0L. Ill check on alldatapro.com for the info on the databus. Everything ive read, has said that it was databus. But ???? It was an 03 F-350 Superdudy. I didnt even check to verify that it was, I just set up the remote start for 15 sec wait time to crank. Ill post again after I find the info.

I agree, everything I have read says that it is databus too. The thing is, I have yet to find one that didn't have the wait to start wire at the instrument cluster. BUT I have not done a 6L yet. Next week I am doing one so I will see first hand :)

I just looked in Alldatapro.com. It says its the same 01+ that its databus. But you have proved that it can be done. When you do the new one next week, email me. I would like to know if its the same, and what wire you use. I use Crimestopper, that has a built in timer option, but here in Montana.....somtimes 15 sec is too short and 20 sec is too long, depending on time of year. I would rather hook it up to the light.

I will do that. My information also says it is databus like I said but does offer a solution which is to hook it directly to the glow plug relay. To me this is the next best thing and would work better then the timer. I am in Canada and a timer just doesn't cut it. Our temperature can range here from -30 to +100. That is the difference between no glow plugs and 30 seconds or more of glow plugs.

I' ve done around 4 or 5 2002, 2003 F-350's Deisel and I had to use a pulse timer, also it probablly is easier then taking the dash apart???

The dash is super easy to take apart. I don't cut corners with diesels by using a timer. If you have ever owned a diesel you can appreciate how important it is to have it wait the right amount of time for the glow plugs. I am curious Bnluis, did you actually check to see if the glow plug (wait to start) wire was there or did you just assume because of the information you had?
Posted By: BNLUIS

You know how it works the information said it was a databus. I called tech support ( DEI of course ) So I wired it as tech support said to. Don't get me wrong I rather use a wait to start wire it is much more relaible. You know the car will start as soon as the glow plug goes off. I always used the wait to start wire in older Fords and for all Dodge pick up Diesel installs. Did you use use a diode ? or any tips Maybe I will try it next time. Then again, you're in Canada, trucks might be different??? ------------- Luis
