Ok so it works whe i have the switch and main into the hot side of the relay. However when i hook the switch into the brown relay it's a no-go. I thought that wire was "hot" when the key was on? Do I have to run the switch lead into the fuse box?



Now I'm confused. You need to post what sort of relay you are using so we can help get the contact layout figured.

The relay should have at least two contacts.

The pump hooks to one contact

The big hot feed goes to the other

The relay should have two coil terminals

One gets grounded

The other goes to your small wire going to the switched power

To check your relay, unhook the pump lead and turn the key / switch on/ off. You should hear the relay click, might need a friend.

Or turn on key, pull switched lead off relay, it should drop out, hook it up, click in. Turn off key/ switch, recheck. Relay, of course should NOT click.
