Recently picked up a 98 softail Custom and it is missing the bottom of what I believe is the relay box in the rear fender under the seat. I'd like to order the part but can't figure out what it is called. Any ideas?

 

Its called the Electrical box assembly, Houses the relays. Part# 72147-96.
Seeing you own an Evo, you'd probably be better post your issues over in the Evo Classic section. A lot more knowledge over their when it comes to the classics...

 

Okay thanks very much 98. A classic - that cracks me up, not wrong but it's funny.
