Fuel Pump Hot Wire?

Quick question: 87 RX-7 TII, which wire going to the fuel pump is the hot? On top of the pump I see 2 blacks, a blue and a red. Im pretty sure its the red but I have no way of testing it right now and I cant find the manuel...

Thanks,
Ryan

2 are thicker, and 2 are thiner. the 2 thicker ones are for the pump. I think mine were both black. one had a white strip. I would guess the striped one was power.

this was for my S5... and memory.. so check that.

the 2 thinner ones are for the gas gauge.
