If the sensor is not on the wire right by/with a ring terminal (put that on the neg post if it is--I don't know why the neg), then do exactly like you did--tape it to the side of a battery or jam it between two batts.
Unfortunately that only tells your charger what to do, but you can't read the temp. AGMs can heat up if kept on a higher voltage charge after they are full and should be dropped to a lower, Float voltage.
Each AGM can be a little different for how they act like that. Have an IR temp gun handy so you can measure the temp of the side of each battery if you feel it getting warm while the other batt still feels normal.
