Old ford 2200 glow plug connection

[TheEntertainer]

Hi guys, hope you all had a great weekend.

My fil has an old 38hp 2200 ford tractor and he want to connect the glow plugs back up. Does any know which connectors they go on. See pic for current setup. I’m pretty sure its the loos wire (yellow). Just need to pick the right terminal.

Thanks all

Hi,
Found a pick on the web and it looks like the far back right is the glow plugs, so that make it worst as they aren't glowing. Where an how do I start trouble shooting?
Thanks
