relay box

[kglowacky]

Help . I am wanting to buy a aftermarket relay box with a fuse strip built in it for both my fuel pump and cooling fans.. I have been told for the fuel pump I need a 4 pin 30 amp. I am assuming for the dual cooling fans I will need the same. My question is everyone seems to want to sell me a 5 pin relay not a 4 pin. . Ebay has a great bare box but I am trying to buy the complete system (Relays and fuses included) as my wiring knowledge is little. Anyone have a source for this. I seen the box and relays on another thread and love the way they look. Thanks
