does the in-dash switch for the tank switch left or right have full amperage going threw it for the fuel pump power ?

i am not using the oem system . this was extra parts i had and making a transfer switch setup to fill the extra dash hole .

i want to send power to the pump threw the switch only .

i pined out the switch so i know what pins i can use for this .

just need to know if i can use just the switch for free flow transfer of fuel to other tank with a stock tbi pump/sender in the tanks . or do i need a relay for this ?

thanks for any help guys .
