So with my results of 14 ohms TPS-to-battery, 17 ohms TPS-to-10-pin connector, and 22 at the 10-pin when jiggled, what would be your next investigative step? Also how could the resistance be higher at the 10-pin than at the battery? Wouldn't the resistance over a longer circuit have to be equal or higher?
Did you disconnect the battery before making resistance measurements? That is generally a best practice to avoid the small voltage drop that occurs when a circuit is powered up and in working mode.
