yea i have never understood that either,i had the same comp on my mazda and it had a relay but burned them up 2,the wires are 2 small on the relays 2,i have found that the best way 2 run it is the way i have it set up,the comp runs strong and nothing gets hot and breaks,i know if i hooked it up on a relay i would deff bring a few and have a extra psi switch
what wires are too small on the relays? the ones inside of it or the ones on the pigtail harness that some of em come with?
i usually ground the 86 pin, hook 85 to the pressure switch wire, then 87 not 87a gets a 8g wire to the compressor and, 30 gets a fused 8g wire into it.
the wiring on the pressure switch somewhat depends on the type of ps. You can also add another relay in the mix to make it so there is only power to the pressure switch when the car is on.
