Custom harness

Thank you for the pics!! And otateral what is the advantage of buying a wiring harness? I think all I will need is some wire (I do residential and commercial electrical work so I can get 10 and 12 ga wire for free) a fuse block and some relays and connectors. And dust off 440 where did you get your fuse block? Thank y'all for the replies

it is a HAYWIRE for street rods I picked up at a swap meet, shop around on ebay and other places if you arent in a hurry...I decided to wire it my self when I saw the cost of prefabbed harnesses...
