I am using pin 1 (Blue with red stripe) and pin 4 (Black with gray stripe) on my 16 pin mirror connector. I bought the Invisicord with micro taps and the power tap on pin 1 was very tight, but the ground tap on pin 4 was much easier to install. I used a standard straight pin to the make the gap on pin 1 big enough to slide the micro tap in with a pair of needle nose pliers.
By the way, I have the Redline with the new BS/RDR software and it beats the 9500 ix by a long shot on all the distance tests because it uses the superior M3 dual-antennas. It also consistently beats the V1 in very tightly controlled tests.

I use Highway mode for the long roads in Texas and AutoNoX mode for driving around town. (AutoNoX turns off X-band and reduces most K-band falses from big-box-store door openers)
If you want the most distance in a windshield mounted RD, choose the Redline. Coupled with ****** Live, you get the best distance on the highway and the GPS control with Red Light Cameras, etc. for driving around town.

I agree with most of what you're saying...except ****** Live. ****** Live is a joke and is way too buggy to be useful.
In regards to the Redline with BSRDR vs. the V1 with V1C and custom sweeps, they are very close with the Redline edging out the V1C. But personally, I can't give up my arrows for situational awareness. And both detectors will probably be sensitive enough for a I/O save even if off-axis.
