find the wire that goes to LED from the GP relay, and use it as your switch ground.
(You will need a three terminal switch for that)

Im using the starter solenoid as my relay. Push button activates solenoid and glow plugs glow. The button i have is only a two terminal.

I used the stock wiring to activate the relay to switch the juice to the glow plugs. Light on dash works just fine. Listen to the relay clunk off as the light goes out.
Or nearly so.
Seems like a minor delay is present.

I would do that but the car was a petrol engine before so no glowplug wiring that why im doing it with a button.

As far as i can tell i need to plug a wire into the front of the fuse box where the glow plug L terminal would be plugged into. Since this isnt a diesel fuse block will that have the ability to receive a wire into it?

Now just have to figure out how to activate the light when I push the button. It looks for ground to come on.
Are you talking about the yellow dash/cluster light?
Doesn't sound like the momentary switch has a light.
Pretty easy to put another LED in the space next to the glow plug light, if you plan to use a stock relay/timer later.

Yes trying to make the stock glowplug indicator led come on when i hit the button. Its trivial but i want to figure it out.

gotta ground lead to led... so he needs o invert its power on to completing a ground...
so 1 ide of push button to ground...
'
other side goes to led feed.. and to terminal 85 of a fog light relay under hood..
----------fog light relay......------ ued fo ra inverter..
30 and 86 power from batt
85 your push button
87 to starter siloinoid.. for glow plugs..
then wire in you rglow plugs..
this design allows you to use a nice small rat shack push button... and makes the light in dash cluster work too.. pluse feeding a ground thru firewall imo better then a power feed..

Is this a mk2 car? if it is this is easy.If you've got the car the engine came out of, take the glow plug relay out of it and plug it in to the gas car. Same fuze panel. Now take the wire that came off the back of the panel in the diesel car and install it in the former gas car. Hook it up and you are done. 20 minutes and you are done, no hacking. You won't have a light on the where it belongs, but if you really want one you can add it. Just wait 10 seconds or so after you turn the key on and the car will start. there's a default circuit that will make this work without the temp sensor that they use, been running mine this way for 2 1/2 years.

Tested out my plug into l terminal on fuse box in my mk2 and it worked. plugged in a wire and grounded it and glow light came on. Did not work on the passat so i pulled the wire out of the pigtail grounded it and it didnt work so im guessing the led is burned out...

OR you could add the LED and cut the trace that feeds power to it. Ground that side of the LED and run the other side to the the GPs. When the GPs get juice the GP light on the dash glows.

Got it all figured out. Was grounding the wrong wire. When we made the harness for my cluster we use a different colour than was stock and we didnt pluf the glowplug wire into the connector for the very reason of when i set up my glowplugs. Found that wire plugged it into the connector ground #9 or "L" terminal on the fuse box bam glowplug light comes on. I found a male 2 pin connector and pulled on of the spaded out of it and it fits perfectly into the #9 terminal.
