MY CAR WAS ON FIRE. Does anyone know how to change these connectors and what is the part number for these?

Those are your coolant glow plugs. While you certainly can replace them and the wiring, I think in this case I would clip the wires and tape the ends. Clean the crud off the glow plugs ..gently so as not to cause a coolant leak and call it a day.

Coolant glow plugs are supposed to help heat your coolant faster when the weather turns cold, they are not monitored by the ecu so no codes when they stop working. Most of us at this stage in our vehicles age probably have non functioning coolant glow plugs and don’t even realize it.

It looks like the fuse that controls the coolant glow plugs is a 50 amp that is located in the fuse block on top of the battery. I would suggest pulling it but I’m not sure if it controls anything else.

I would also check that battery fuse block for melting which is a common problem with these cars.

I have the same list. I believe that will be the first fuse on the left of the block. You could try disconnecting it and then see if it affects anything else. Such as your regular glow plugs or the starter or any other system. Once disconnected it would not start another fire.

You honestly saved me.

Here it is, I think I did a good job.

I didn't touch the glow plugs, do you think it's enough just removing the connector and the little plate under?

Your gonna need a new fuse holder too , that 30 amp green fuse to the left there is already starting to melt the housing , it’s a common issue , too much corrosion builds up on the fuse prongs and cause high resistance increasing the current flow and it starts to melt things there.

Yup that green fuse is also looking sketchy.

Has the removal of that wire affected any other system?

I would probably try and clean up those burnt glow plugs though you should be careful not to create a coolant leak.

I actually haven't driven it yet since I need to replace my brake vacuum hose, I might actually just park it for the winter
