How To - Glow Plug Override

Guide for Glow Plug Over Ride
While Maintaining Computerized Glow Plugs

This is a guide to help you install a switch for you to have the ability of extending the glow time. This is helpful when you live in older climates or if you have AC Delco 60g glow plugs. I only suggest installing this if you have self regulating glow plugs. This is a fairly simple modification and if you set everything up yourself you will save quite a bit of money. Most kits for this will cost you over $100, but if you follow this guide you can do it for under $40.

Parts:
  • Ford Starter Solenoid [$12 - Advance Auto - 5470277 (S58Z) ]
  • #6 or 8 Gauge Wire and Connectors [$14 - Tractor Supply Co. (6 gauge, 2x 24" wires) ]
  • Momentary Push Button Switch [$5 - Tractor Supply Co.]
  • Switch Wiring and Connectors [In garage]
  • Add a Wire Fuse Tap [$7 - Advance Auto - 5080114 (BP/HHH) ]
Total Price for Me: $38
Estimated Time: 1hr 30 mins
Degree of Difficulty: Easy

Step 1:
Disconnect battery grounds and then take off the nuts that hold the power lugs on the glow plug relay.

Step 2:
Mount the solenoid in your place of interest (I mounted mine where the Baro sensor was located and relocated my baro sensor).
Hook up switch wire to the "S" lug and feed wire through firewall, make sure you have enough wire to go to switch. Below is where I mounted mine:



Step 3a:
Remove your dash bezel. You can do this by pulling out your cup holder a little bit, dropping your steering column all the way down, and for automatics putting shifter into "1". After that pull the corners and along the top on the bezel. Only thing holding it on are the clips.
After the bezel is loose, pull it away from the dash enough so you can unplug the headlight switch and cargo lamp, and 4x4 switches.
Note: You do not need to remove your bezel if you place switch on one of the two extra switch panels, just pry those out and you can feed wire through.




Step 3b:
Drill where you are going to mount your switch and mount it (you have one shot). The next thing you will need to do is run the power to the switch. Using the fuse tap, tap into a fuse that is only has power when key is on and run that wire to the switch (I used Cruise fuse).
After the switch is all hooked up (solenoid and power) go ahead and hook up everything behind the bezel (headlight,cargo, 4x4 switches) and mount the bezel back on the dash.





Step 4:
After everything is done inside the cab, go back and connect the the Solenoid to the Glow Plug Relay. Do this by using the #6 gauge wire and connectors for the lugs. It shouldn't matter how it is hooked up as long as you have one lead on solenoid and one lead on relay, and the other wire on the opposite side of the relay and solenoid. See pictures:
Note: Do not over tighten the nuts on glow relay. New glow relay is $42.






Step 5:
Make sure all the connections on the relay and solenoids are tight and no bare wires are touching that shouldn't be. Hook the batteries back up and test. Turn on key, wait for the glow light to go off and push the new glow button. If working properly the glows will work (hear the click) and the WTS light on dash will light up (97+ WTS light will not light up, the light is computer controlled). If this happens then you are done .

Note: On 97+ trucks you may want to install an extra indicator light to make sure your glows are working.

I believe you have the solenoid upside down.

I mounted it so I didn't have to remove any insulation, that is why it is mounted where it is... Not sure if it is considered upside down or not, if so doesn't matter because it still works .

A little off subject but I noticed your PMD is mounted on the intake. I know I heard other saying not to mount it there. I got mine mounted there temporarily till I decide to snip and crimp my own cable or spend $30 some for a made one.
Do you have any problems with yours mounted there? When I had my engine running for the first time the other day I was doing some temp checks and my heatsink was around 120 degrees so I checked the one on the pump and it was 120 also. This was while idling.

Looks like you got the solenoid mounted right. Nice write up and pics.

Now if we could just get that ground wire off the FSD cooler and put it back where it belongs.
Hmmmm? Things we notice about other peoples trucks.

Thanks


Why change something thats not broke? lol . The way my heatsink is mounted and the way my batteries are grounded, I would say my fsd ground is good. Plus its been like that (as stated earlier) for at least 3 years. That is how it was when I first bought the truck.

Would'nt that also be good for a temporary bypass for some glow plug problems in the future.Not meant as a repair but till you get time for the repair.
