458 - vacuum pumps issue with power control wires

Have been unlucky with a real **** experience.
We changed the exhaust on my 458 and everything went perfectly smoothly, but of course the accident had to be out and the one wire that controls the vacuum pumps for the damper to hit the exhaust and be melted and short-circuited due to the heat.

We have switched plugs and cannot find fuses or relays, so we can get the error rectified.
It is a fuse or relay a place that needs to be changed ....I hope .......
If we switch around connectors, damper control works perfectly .... It's the left side that creates the problem ....

I hope you can help with wire diagram or solution.
