SPF Oil Temp Gauge Replacement.

[jhv48]

Three months old and the mechanical oil temp gauge went south.

Ordered a new one from Nisonger and it should be here this week.

My question is this: How the heck do I pull the temp wire end and the large end nut through that small hole in the firewall that also has my water temp wire and my speedo cable going through it?

The hole in the firewall, along with the rubber grommet, appear to barely be large enough for the hold down nut to go through alone. How do I slide out the old wire and nut without removing the speedo cable first? There has to be an easier way. Or should I just drill another hole in the firewall and route just the oil temp gauge wire through it?

There doesn't look like there is enough room to slide out the old cable and nut through the firewall hole while the other two cables are still there.

I know there has to be an easier way to remove and install the new wire.

Or am I just misjudging the size of the hole?
