Sending unit mystery for 1972 TCS system - need sage advice
Seeking help from electrical gurus.
The GM part number corresponding with a sending unit I need for the transmission controlled spark (TCS) system in an original 1972 350 small block produces units that have a pair of male spade-type connectors for the electrical harness but the original sending unit has a single spade-type connector. The harness has only a single female connector.
Photos of the original single spade sender, an excerpt from the parts catalog showing the number, and one example of double spade sender with the "correct" part number (multiple additional examples exist).
Is it at all conceivable that the original unit was superseded with an example having two connectors and that one of the two connectors would suffice for the TCS system in my engine?
