you probably know all these already. me, being a builder, did not I only found out about five years ago you can get relays with built in fuse holders. bolt it somewhere to allow access to the fuse and it looks pukka... No more inline fuses flapping about. At roughly the same time I also found out you can get actual relay connection blocks, that look so much better than lots of naked spade connectors crimped to wires. Its easy to remove the tabs too, so you can swap them around depending on what colour tail you want to use for permanent live/switched feed etc. brilliant. Finally, last summer my bro in law showed me these luter connectors you can get. normally, I try to spline wires together then solder them then heat shrink over. These luter jobbies you just feed a wire in from either end so the bare strands are in the inbuilt solder band, then apply heat via a small nozzle on a hot air gun.dunno if the solder has a low melting point or summat, but it melts, bonds the wires, and then heat shrinks over the join. cleverly thought out too...one side has a slightly larger bore, meaning you can splice thicker cable to thinner, or if taking a spur off (as I did for a switched feed off the back light), you can feed two wires into the larger bore to meld into the single wire on the other side. all three things together make for a pro looking job that you aint gotta worry about. I still used a big heat shrink to contain all the wires and look neat, but its nice to know each individual joint underneath is both strong and watertight. And it looks factory, along with taking the worry outta leaving the grips on. took the xjr out today with both heated grips and underjacket and it was berluddy lovely. the trade off for three hours out on the bike was an hour to wash the salt off and drown it in fs365/wd40, but worth it.
