I mounted up the '93 H-Car set up. What it has is a rail that mounts
8-sealed relays, and 2 bussed delphi 8position maxi-fuse holders. I'll probably
only use 1 fuse holder. Plan is to run short 2ga from battery to input
buss for fuses. Other end of each fuse will go to each relay high-power
input. I'll mount a main ground for all the relay coil activation grounds,
 and other relay wires (high power out to load and coil activation input)
will be coming in from the side. In order to wire it properly (without
butt connectors) the folowing terminals & acc. are needed:

Maxi-fuse terminals
800 Maxi-fuse Female
    12065916 (8) (4-5.5mm wire(8ga))
    12110127 (8) (2.5-4mm wire(12ga))

Sealed relay base terminals:
280 Metri-pak tangless female sealed
    12110853 (16)
    12125409 (16)
280 Metri-pak cavity seal (to seal off the unues 5pth pin of some of the relays)
    12010300 (10)
280 Metri-pak cable seal (color determines cable range)
    12015323 (green) (for 18ga) 2.75mmwire (16)
    12015193 (blue)  (for 12ga) 4mmwire    (16)

And the Required tool to remove 280 metri-pak terminal. The one I have of yours
now is a wide pick, good for  56,59 series and the 800 above. But it's way
to big for the 280 series, I can't find which tool# is the right one to
remove those. I didn't try that hard to get them out, they are tangless,
so I'm not sure how their held in. The crimper is the same, so yours works for these too.
These can all be bought from various places, but for some reason, they are
not so cheap, they are running like $0.89/terminal, and $0.39/seal. The
800 are like over $1.00/piece.
