Go to a local mom & pop computer repair store where they build & service computers (not somewhere like Best Buy etc.) & ask them for a CDROM to Audio cable . It'll be a length of 3 wires (red , black & white) with a 4-pin connector at either end . They come in various lenghts , try to get a long one (maybe a foot or so long) . Cut the wires in or around the middle . Plug BOTH ends into the back of the clock ... instant 8-pin connector . With very little effort you can move the wires around in the connectors by simply moving a little tab near each wire's pin . Move the wires to where they're needed & splice into the radio harness & the anti-theft light . Easy as pie ! I learned this trick while researching how to do mine to make it removable (for trade-in time) . It works like a charm .
Good luck !
BTW-The guy at my local computer store didn't even charge me for the wire

. He had a whole bin of old wires removed from computers over time .
