As far as I've researched the 66 barracuda has the limiter in the fuel guage. I've had this dash apart before and located no external limiter. Also if I have my information correct based on previous posts. To install the external i just need to cut the wire inside the fuel gauge then hook a lead from each finger of the external limiter to the lugs on the the fuel gauge? However does it matter what side goes to which on the limiter and the guage is marked with S V I on the lugs. Which lug goes to which side?
