I Just bought an fm transmitter and since i hate the stupid plug and
all the wires i hard wired it to the car. first is this safe? also my
power supply to the transmitter is always on even when the key is out.
and the red LED on the transmitter is always on. My main question is,
is it ok to leave it on all the time?, and will it drain my battery? i
already did it to my sirius radio. My transmitter is a Monster brand
one, i provided a link below for reference:

Did you wire it to the cigarette lighter wiring or somewhere else? If
you have it on the accessories/on wiring, so that it is off when the car
is off, battery drain is not an issue.

I suspect that after a 2 week vacation with the car parked in the long
term lot, you'll need jumper cables to get the car started and since
car batteries don't handle deep discharge, you'll be getting one of
those, too. Why don't you just connect it on the accessory side of the
power? Do you need it to function without the key?

As far as 'safe', do you have a fuse in the +12 line so if something
shorts out, you don't start a fire or damage the wiring harness?

Dumb, dumb response. That sort of day....... rewire your tx so it runs
off the cig. lighter, as I (sort of) implied.

Cheers.

I just disconnected the ciggerect wire harness and connected it to my
transmitter. both my cigar plugs are always on even when the key is
out. So it wont drain or cause any harm if its on with out the engine
on for say 14 hours somtimes? also how do you just connect it to the
accesorie power, please guide me through. thanks!

Wire it to one of the interior lamps. Of course you'll have to drive
around with the door open. This is fine for the summer though.

Look down on the fuse block. Lots of cars have a power terminal there.
("fused Ign" or something like that)
It really depends on the year, make and model of the car to get
detailed advice.

Sweet all done! drilled a hole in the center consul, and istalled a hot
LED switch connected both the sirius and the transmitter to the switch
then soldered them! looking very good!

You have got a fuse in the 12V feed haven't you ?

Cigar lighter socket can provide some serious current so I suspect its fuse
might out-live a short and rather burn another potentially weak spot in your
wiring. It would be smart to use a small fuse.
Thin Cu wire can literally burn when shorted over 12V which can burn you
severely or do some damage to the car.
