What harness are you running? Engine and vehicle?

Mount the relays close to your battery source. I like to mount them near the fans around the horn relay or junction on Chevy's.

What brand engine harness or who put it together. Did it come with a relay block?

There should be a fan 1 and 2 wires from the PCM.

You can run a 10g wire from the starter BAT+ to a junction block or circuit breaker for the relays. Mount them up on the radiator support.

Here is one option. Not the lowest cost but gives you dual speed fans and an option of A/C control.

Pretty dang cheap if you ask me -- given what I pay for SPAL relays @ $34 a piece!
