need relay help

how do i wire up the relays for my compressors. i have the dual 380s.

any help is greatly appreciated

87 - 12 volt - recommend you make this a switched power like off the fuse box.. only on when the key is on
86 - remote turn on - hook to pressure switch
85 - ground - chassis ground is good
30 - is additional accessories - out to the compressors

thanks man.

exactly what i needed

so what do i hook the main feed to the compressors to?

This might help.

so i need to put the pressure switch in series with the ignition line to 87.

then hook up the battery feed to 86?

best to do it like it shows.... i did mine a little different because im running an edc instead of an electric compressor

relays haha!! funny i was just learning bout these at school! in..uhmm.. mech tech..

too bad i cant remember anything lmfao

do yourself a favor and just get a ford starter solenoid.

Just wire it up w/ a standard 4 pole relay.
Positive from the battery to Pin #87
switch or pressure switch will be wired to pin 85
ground (for the relay) to pin 30
Positive from the compressor to pin 86
