In post 84 you mentioned the red wire with fuse holder and that you would describe connections later - can you elaborate?...I believe I got that right since the fuse holder itself appears to be keyed and will only slide into one slot in the fuse panel anyway...
But I am wondering if you can shed light on the relay situation. The hitch came with one but I'm not sure where it goes or if it's even necessary. Various other posts online refer to relays L, K and U but it seems there are different opinions on which is necessary (if any).
Thanks for your hitch installation guide, it was spot on and made things easy for me...
picture of my Beige door sill PN 66890142 love how look at night, this is my first MB with door sill.
Does anybody know if the electrical for the door sill is in for the GLs that did not have this option. I know some times the wiring harnesses are standard even if the car does not have the option and the plug may just be under there. Anybody know? I would really like to upgrade my GL with these oem parts.
