To start order new glow plug harnesses. They ARE GOING TO BREAK when you remove them. next get a 10mm long socket and a ratchet and go to town. Pull, replace, wash, rinse, repeat.
If it's worth the effort to you you can pull the valve covers and pop the harnesses out from the inside. Otherwise prepare to fight the old ones until they are an unrecognizable heap of wires and plastic
with the glow plug harness tool it is very easy you can buy them on ebay, mine broke because im from NY with all the salt, i was able to reuse mine even when the metal part of the harness broke because the proper tool doesn't break the connectors
