I finished the installation of the Banks exhaust brake on my 2006 Ram today. Installed the vacuum pump and fan belt (not shown).
I expected the fan belt to be the most difficult part, but it wasn't too bad. The installation of the switch was a pain! I wanted it on the dash up near the instrument cluster rather than down on the knee panel like Banks recommends. Seems ripe for breakage rhere. That required disassembly of the dash, which would have been much easier with smaller hands, more elbows, and removable eyes to see right spaces. I pulled the cup holders and console out first, and found the previous owner's iPod.
I almost stopped and ordered a new stereo since I was that close.
But I really wanted this job done, so I pressed on. Now that I know how to disassemble the dash, I can get to the radio fairly easily. Finished the wiring and buttoned everything up for the test start. Took a little longer to start than usual (maybe because the PCM had to be unplugged to wire up the brake controls), but when it fired up with the brake on, everything worked as expected. The brake activated immediately to speed engine warm-up on a cold start. Lighted switch in the lower right indicates brake activation.
