Anyone ever heard of doing this? Got any info on how to wire it??

My #8 fuse keeps popping, even with a 20A fuse installed and a new blower motor. I can run my blower all day, but once the AC comp kicks on it pops the fuse.

My mechanic recommended adding another ground to the compressor and doing this relay harness mod. Can't find much info on how to wire it though.

I know there's a 2 prong solenoid on the AC comp and there's an ice cube relay for it atop the driver's wheelwell. Not sure exactly how they work...
