Larry,
I would say spend the coin to get the MotorCycle Cruise system. You have the skills already to install it yourself, based on what youve shared with us here in this thread. Its an excellent system which is bulletproof when done paying strict attention to instructions. It took me a full day for my initial install, it is rather involved, but not that hard.
When I bought my unit back in 2007 for my 06 Advanced Edition, I was still a bit intimidated by all that bodywork on my $15,999.98 wonderbike, I was hesitant to disturb any of it. Their excellent installation manual, loaded with photographs, took me by the hand and showed me every single fastener and body panel to remove for proper access. About the only thing it didnt show was the charcoal canister that my California emissions compliant possessed. Thats all I needed to break my cherry regarding servicing my full bodywork FJR.
One thing I will recommend, if you buy the system, it typically has the actuator mounted under the seat, however, the AE bikes have an electronic Black Box in that location, which forced them to find another spot. They chose to mount it under the right lower fairing just ahead of the frame and behind the radiator. The control pad was also relocated to the right hand grip because of the lack of a clutch reservoir on the left handlebar. I think it is a superior location. Tell them you want the AE setup, only with the non AE harness because your bike has a clutch handle; they omitted the pair of wires to a nonexistent clutch handle on that bike. Other than those two details, the system is the same for both the AE and non AE bike. And by the way, the 07 and 06 bikes are identical , you wont find any issues there.
Ive also installed the AudioVox system on a friends 08 standard FJR, and I wasnt nearly as impressed by it, having to have to be creative with setting up the beaded chain throttle linkage. I much prefer the fully engineered cable interface, and the extra safeguards the electronics provide in the MC Cruise installation. It is a system designed expressly for motorcycles, not an adaptation of a generic automotive unit - much safer in my opinion.
You wont be disappointed with the system once in place. It will be money well invested.
Just sell more sandwiches.
