I purchased my 01GL1800A from the original owner some years back. It is a US model and I picked it up in Columbus OH. He was an electronic engineer and did a lot of mods himself. There has always been an issue when I remove the left front pocket and try to replace it. I have always had to fight for space with a large wiring harness. Today, since it is raining and I am working tonight, I decided to tackle the issue and upon taking everything apart I have found the harness photographed below inline between 2 factory connectors. It appears to have some sort of electrical filter. Does anyone know what it is for and if it is required?
