Where/how to get 12VDC

Kickin' a.s and Takin' Names - 24 Mar 2008 03:56 GMT
I'm hardwiring a Sirius satellite radio into my 2004 Explorer and I
need a source of 12VDC.

Beneath the steering wheel, in front of the driver's knees, is a trim
panel that can be removed by taking out two hex-head screws at the
bottom of the panel and popping out the two clips holding the top of
the panel to the dash.  Removing this panel reveals all the stuff
underneath and beside the steering wheel, including the fuze box.

When I check the fuse diagram in the owner's manual I find that fuse
#9 is not used for anything.  I assume I could somehow stick a wire
into that fuse location and pick out 12 volts -- or, has anyone seen
any kind of adapter that plugs into a fuse slot for this purpose?
After I get a source of switched 12VDC, I'll run the power cord for
the Sirius radio through joints in the trim down to the area beside
the steering wheel and tie it into the 12VDC.

OR -- maybe I should tie the power for the Sirius receiver into the
power for the radio -- what color wire is the main 12VDC lead for the
radio?  The radio in my Explorer stays on when the switch is turned
off then it goes off when the door is opened.

Thanks.

I like to use the Littlelfuse Add-A-Circuit products for this
application. See

Thanks -- exactly what I was looking for -- now if I can just find it
-- I live in a, uh, "rural" area.  Nearest auto parts place is 15
miles -- I'm headed in that direction in 2-3 days and will see if they
have it.

Ed --

I purchased two of those adapters to mount Sirius radios in my '04
Explorer and '97 Mazda B4000 -- worked perfectly!!!  Thanks for the
tip.

I ordered six more of them for my electrical toolbox just in case I
need another tap.

If location 9 in the fuse block is hot and there is no tap on the load side,
you can easily install a tap and a fuse and get yoru power from there. You
can also plug a wire with an inline fuse directly into the tap that is
already in location 9 and get your power that way.

I would select a power source that comes and goes with the radio.
Alternatively, you can select a constant hot and set the Sirius to turn off
after a certain period of time so it does not run all day while you are at
work. The problem with this is that the receiver will shut off in the middle
of listening to something you like, and you have to wait a few seconds for
it to spool up again. I had my satellite receiver connected to a switched
hot, and then set the receiver to never turn off while power was applied.

Thanks for the suggestions.  I'm going to look for the radio power
source and try to tap that so the Sirius goes on and off with the
radio.

I purchased the Sirius professional vehicle installation kit that
contains a separate power supply that mounts under the dash,
eliminating the plug that goes into the dash outlet or cigarette
lighter.  The kit also contains the FM direct connection adapter that
feeds the output of the Sirius directly into the radio -- I have one
on my Mazda truck and it eliminates the interference from FM broadcast
stations.

You are gonna like the direct connect thingie. It works way better than the
FM modulator, having said that my XM radio with the XM-brand FM modulator
worked very well -- the sorry bastards that stole my truck are likely still
enjoying it.

In any case, you are going to have to figure out how to pull the radio to
wire in the direct connect thingie, so you can find the radio's hot lead --  
most likely to be RED -- on the back of the radio. You will need to unplug
the antenna lead from the radio and plup it into the direct connect thingie,
and then plug the antenna lead from that into the radio. This sounds
complicated, but the most difficult part is the physical effort needed to
extract the radio from the dash board. The rest is easy after that.

Thanks for the suggestions.

My Sirius order arrived today -- Sirius radio with the various
mounting options, antenna, and the professional installation kit with
includes a power supply ( 12 VDC in, 12 or 5 VDC out; power cords for
12 and 5 VDC to go from the power supply to the Sirius radio; direct
FM adapter ( car radio antenna plugs in one end, lead carrying output
from Sirius plugs in the other end, cable goes to antenna input on car
radio, when Sirius is turned on the car radio antenna is disconnected
electronically ); plus all sorts of extra mounting stuff, wire, and
the like.

I figured out how to pull the car radio -- have to us a thin-bladed
knife or putty knife to pop off the trim bezel which exposes four
screws holding the radio in place.  Think I'll connect everything and
stuff power supply and FM adapter in the hole behind the car radio;
mount the Sirius at underneath the A/C controls; run wiring out
through spaces in trim panels -- should look good -- have to be
careful as this is wife's vehicle -- in my truck I run Sirius, GPS,
and ham radio with wires running all over hell and back.

THE ANTENNA
This is a magnetic mount gizmo that they will tell you to stick to the
roof -- where the ner-do-wells will all see it. I suggest you put it in the
center of the dashboard as near the windshield as you can get it. A small
dab of super glue or perhaps some velcro to hold it where you want it. The
beautiful thing about radio waves is they will pass through glass without
any problem at all. If you can keep all of the hardware inside where the
ner-do-wells actually have to get nosey to find it, you will be better off
as opposed to a specially designed device magnetically attached to the car
with a conspicious wire trailing over the edge of the cab and into a window
... you get the point.

I drive a BMW 3 Series, and I can wedge the antenna under the base of the
windshield and it holds itself in place, the Wife's car might give this
ability too.
