After taking the original L-48 heads off my '73 I noticed there were two "temperature sending units", one on each head. In all the excitement I forgot which one came from which side? They both appear to be factory original as one has an AC par no. 93B-232M and is a two post device. I know I only pulled one wire off this one! The other post was kinda bent over with nothing attached! The other unit is a single post device with no part # other than "AC - MADE IN U.S.A. - 12 VOLT". My temperature gauge DID WORK before the tear down. Which piece is which and what side does it go on for a '73?

Thanx,

Single post goes on drivers side, double post goes on passanger side. For more info on the double post check out The '73 Spot. Got to Techinical Info, select Emission listed under "New" and look at the TSC system.
