Has anyone installed a Z2 in a 2002-2005 Thunderbird? My certified Pioneer install shop went to the speed sensor wires on the wheels but neither wire did the job. We then used the auto volume speed wire that went to the radio. I got a irratic pulsing of numbers from zero to 17 but mostly zero. Someone suggested tapping into the brown wire in abs line at the rear wheel before going into ABS module. Does that sound logical? Have not tried it.
Somewhere in these attempts we have been overlooking something or simply not sharp enough to figure it out. Help.
