I don't know if it matters , I put my fuse/holder between the battery and # 30 of the relay and tucked the holder under the strap of the battery hold-down . It may be better to put the fuse/holder between 87 and solenoid .
I would post some pics but , I am not smart enough . The wire gauge was 16 ,14 or something . I went to NAPA and got $35 worth of stuff because I couldn't find anything . BTW I use uninsulated butt connectors and heat shrink .This keeps out water intrusion and acts as a strain relief .As I have stated , the new relay carries the current to the starter and not the mini-relay in the relay holder . I have used this before on Lucas starters . They burn UP neutral and ignition switches like crazy .
A special thanks to K-R for putting down in print my thoughts .
