alerternate 12v source other than fusebox?

[tisker]

I am currently wiring in a bypass switch for the aux fan. I have everything wired via basic relay, but I'm not getting power to my switch or relay. I jumped the relay from 87-30 and the fan came on. My switch has a light on it to indicate that its on, and I'm not getting power. I have tried a couple fuse locations varying from constant to ignition. Any help to power this swtich would be much appreciated. 

the simple relay schemetic i used.

I used a piggyback fuse tap from an ignition only powered fuse in the block. I am pretty sure it was the radio

ok so i tried a tap from the radio as well, nothing. what could be causing a loss of control voltage? i jumper the control side it fires up no problem. kinda stumped


:::edit:::
problem solved. was a silly mix up on my end. swapped my control wires. was checking over it and realized what happened.
