Glow plugs in a Video/Dtt receiver??
New one.
If you mean the van type. Same as a spark plug, they just unscrew. unfit the wire could be clip or bolted on, then unscrew it.
What makes you think you need to? You can check them using a car light bulb, wire it in series with the plug, if the bulb light, plug ok, if no light plug open cct
