[quote name='Rob x-7' date='Apr 18 2005, 03:33 PM']the relay they refer to is for the antennea to work properly, you would add a relay to switch the ground, stock mazda sends out a negative signal to tell the antennea to go up, all radios send out a positive signal to tell the antennea to go up, so when you hook up a aftermarket radio without installing a relay to switch the signal the antennea works in reverse, but that will not blow the fuse, something else blows the fuse.
