wiring up two compressors

I am going to bet getting another compressor (viar 450) but i want to make sure that i wire it up right first.

I already have wires run to the first compressor through a relay, and I'm wondering if I can wire up the 2nd compressor to the same relay? I figured i would just have to up the fuse amperage for the inline fuse, and it would work, but i want to make sure.

Thanks in advance...Pete
