Fwiw,
If one is willing to get a correct crimper and terminals, just make up your own sockets. Clean, no splicing pigtails & so on.
Put the individual relays wherever best suited.
That's what I did when the relays I had screwed on all around the engine bay got out of control. I got the relay mounting blocks that clip together, so gang up as many as you need, I used fused relays. Now they all sit in a tidy row next to the factory accessory outlet/ fuse box. Cheap, simple & keeps joins & connectors to a minimum. Add a couple of spare sockets on the end or at least leave a little extra wire length on the last socket so you can add more later if required.
Having the uninsulated terminal crimp tool & a bunch of terminals is really useful for me as the 'cruiser uses them everywhere.
Cheers
