The 05 speed sensor requires the voltage from the gauge, it's #12 position labeled speed sensor supply voltage. The 08 sensor gets it's supply from the ecu I believe. I guess my question was meant to ask how you jumped it. As for the gear indicator, it works off pulses. We run the voltage readings thru a controller. That much all works fine, it's the speedometer. Hopefully the new adapter will fix that, I believe the last one either had a bad connection or there was noise in the signal cause when the adapter was bench tested it worked flawlessly.
