XM Radio Install - Pics

[fjowner?]

Sorry to dig this back up but i have a few questions. In the pic of the fuse box those "Add a Circuits" are they able to be purchased at an Auto Zone or Radio Shack type store?
I assume the red wire is for the power, the black is ground and the other black is the antenna.
The plug that goes into Aux input does it replace the fm modulator that i use now?
I've installed an XM unit in my Wife's Jimmy but you has to manually turn it off everytime you left the truck because i could not figure which wire to splice into so i used the cigarette lighter. However i did use the fm modulator but i assume that the aux cord replaces it, right? Thanks!

No problem. It's kinda fun seeing one of my very first threads re-emerge after all this time.

The Add-A-Circuits are more commonly found at Discount Auto Parts, Kragen and Checker Auto. For some reason, AutoZone doesn't usually keep a supply of them on hand. (And, be sure to get the "mini fuse" Add-A-Circuit version.)

Rather than directly wiring your satellite receiver power receptacle to the fuse box, you should retain its supplied cigarette lighter plug and use it in line for any required voltage step-down conversion. (Many XM and Sirius receivers require 3-4 volts and a direct connection to a 12 volt source would obviously cause damage.)

I used a female cigarette lighter receptacle to accommodate the XM receiver's male cigarette lighter plug. I then hard-wired the two leads coming from the female jack to the Add-A-Circuit and a ground connection respectively. The Add-A-Circuit itself was plugged into a "switched" fuse slot that allows the satellite radio to be turned off and on automatically, depending on whether the FJ's ignition is off or on.

Yes, the AUX audio output from the satellite receiver is meant to be plugged directly in to the FJ radio's AUX audio input, thus eliminating the FM modulator and providing a cleaner direct signal.

Thanks for the reply, this is gonna help. Is the "switched" fuse slot the same as the one in the pic of the fuse box? And where did you ground the female cig lighter. Thanks again. Life sucks w/o XM Radio.

Yep, that particular one is "switched." As are a number of others.

There is a metal frame that surrounds the "mouth" of the interior fuse box (just inside the plastic). I tapped a hole in the upper right corner and used a sheet-metal screw to combine several different ground (-) points for things like the XM radio, flashlight charger, GPS power, etc.

You can barely see my Phillips head ground screw in the top right of this pic.
