Not the most elegant, but it was the easiest for me. I won't bore you with details already documented, but I'll list differences that may help give ideas to others.
- All routing to trunk was with CAT5 cable except for power and ground (used heavier gauge). I ran two CAT5 and twisted pair power/GND under the floor molding. I didn't even remove the molding, just shoved the wires under.
- I spliced power from RNS-E harness instead of at fuse box ( I was also too lazy to disconnect the battery, but was carefulnot to short anything while working. Do this at your own risk).
- The Sirius and TEL modules are sitting in a cubby hole on the driver side trunk. I probably will eventually hide them behind the carpet.
If I was to do this again. I wouldn't buy a TEL harness. I would just get the connector and route with CAT5. It seems to work fine.
I believe the power to the RNS-E is constant (you can turn on radio when car is turned off), but when I turn off the car, the BT disables. So I don't think you need to use a power that is switched with ignition.
Now my only problem is getting my Treo650 to send favorites and recent calls to RNS-E .
