58th time this will be explained..

So I'll apologize in advance, I'm sure this has been discussed a bunch but I'm a visual learner only and for whatever reason I don't trust myself being correct in interpreting a diagram.

I'm going to convert my gp system to manual tomorrow before I go about putting my new glow plugs in this spring.

So, I'm going to cut the blue wire in half that goes from the mess that heads into the cab.

I'm also going to cut the white wire that goes from the relay to the controller in half. I'm then going to connect the white wire coming off the small post to the blue wire heading into the cab for the wait to start light, and on the same small post that heads into the wait to start system I'm going to install the wire into the cab into my push button onto a good ground. I'm not following the directions I've read most recently word for word but I think it gets me to the same end point.

I think. I have no idea honestly. I'm looking at this right now http://dieselhub.com/maintenance/maintpics/gp-controller/manual-glow-plug-switch.jpg

And I've also looked at at least ten different threads on here, and I stared at the thing for ten minutes today after wiring in my high idle override successfully and decided I didn't have enough beer to accomplish this today.

I feel like by what I read on that article I'm thinking about this correctly, I just need to end up cutting the white wire from the controller, adding my own good ground switch to that post on the relay from the cab, and cutting the blue wire and attaching it to that same terminal on the relay that the push button from the cab goes to where the white wire once lived.

Hell, I can put the wires wherever I want them only 5 of my glow plugs work right now anyways. Thank goodness for the lovely block heater. I'd rather do this before I do the glow plugs just because the truck starts even with the crap plugs if it's at least 50 and not plugged in, so it's not a crisis now that winter is over.

That's basically the same way I did mine, works fine.

The guide that I followed said to bridge the top two posts, which works, but then you have to wire in a switch to kill power to the small top post so that a bunch of electrical solenoids dont stay on all the time and kill your battery. Other than that, its a pretty simple mod and that appears to be a good guide. I also put my WTS wire on the glowplug output post at the bottom right of the relay, before the bus bar.

I got it. I can hear the relay click on and off when pushing the push button and the voltage does drop when pressed. Still basically useless as 3 of the plugs don't work and I honestly think I could just not use them and have the same results but it will be nice once I get the courage to replace them. They look extremely extremely old and part of me doesn't even wanna risk pulling them. If I leave it plugged in for a half hour as long as it's warmer then 40 it will pop off immediately and I can always plug it in where I travel somewhere that I'll be for more then 3 hours for the heat to dissipate away.

Replace them....you will be happier for it.

If they DO NOT COME OUT EASILY...you can thread em back in carefully.....

Who knows...mqybe tips already off and passed through engine...you will never know untill you bite the bullet.
