Doesn't the PCM ground the coil signal? If so, the 85s should go to a key-on positive instead.

Fans and AC are ground. Fuel and IGN relays are IGN triggers. The hobbs switch turns the secondary pump into a dual trigger relay

Can and should are two different things. You can run two electric fans off one relay, but two relays is ideal. You can run two pumps off relay but why not two? Are relays that expensive where you live?
