Hi, new subaru owner. Couldn't get an aftermarket company to supply and fit a towbar to my 2024 outback due to no one currently making them. I have finally had to shell out and buy oem at great expense. 13 pin dedicated Subaru wiring loom with c/van power feeds. Can any one help with instructions or pictures. Can anyone tell me if it needs code updating, Where do the links in the picture go? Thanks Graham
