... In doing your research were there higher power options that would read from a couple of feet (tag in your pocket)?....
Nothing that I could find
There is commercially available system by company called Bulldog, but that is close to $400!
My detector antenna is directly under that front tank cowl that is on my model. The detector box can go anywhere within the length of the antenna cable.
That can go anywhere on the bike really, even in the tail. You only have small gauge wires going between the relay power section and the detector so that is not a big deal to mount wherever.
You want the relays pretty close to the Key-Switch connector however, so that you are not running power wires too far.
I used 14 ga for the relay interconnects
The base reader is available from EBay - pretty inexpensive (search on RFID reader and you'll find it)
The exact same module is available from independent EBay sources in both US and UK.
It will work as-is but I modified it to have a transistor driver output stage for added reliability. This stage will drive up to 600mA (which would effectively run ~ 4 relays in parallel.)
But there are lots of people using the module as-is.
This shows the module with the added components shown above and I have also mounted the LED directly into the box (you only really need it for testing)
If you don't do the output stage mod, then at least connect an additional diode in series with the output, to prevent the voltage from the Ignition circuit feeding back into the device.
The diode D1 is the one that activates the latch - the others across the relay coils are for turn-off spike suppression.
(There is not one across the third relay because relays 2 & 3 are connected together)
This is the interconnect ciruit
(at least for mine, very similar for the 1050)
Clutch switch wire is Black/Orange on 05+ - feeds the ECM
If concerned about interference, you can use an additional relay to isolate this signal to the RFID module.
I used OEM Key-Switch connectors - available from Eastern Beaver and Panasonic micro relays & sockets from same source.
Connector Set 8P250-CNA
20A micro relay & socket
Optional 3-way connector for the Detector Module
3P090WP-MT Connector Set
Diodes you can pick up from RadioShack.
Optional RFID Tags
* If anyone plans to do this on a pre-05 model, it requires an additional mod if you plan to use the clutch switch for the power enable. On those bikes, the clutch switch signal, when open, goes through the solenoid and then through the headlight-cut relay to ground - so needs a mod for that. I will only supply the details for that if required as is unnecessary complication for anyone else.
One quick additional operational note:
Because of the 'latch' even if you use the key-switch, the ignition will remain on, even if the key is turned off and the key removed!
So the Kill must be operated to drop the latch, even for that circumstance.
