all 2nd design: VIN ending in 27373 to 49213, alarm switch located in driver side door lock cylinder & alarm horn located behind driver side front fender, near firewall (includes new wire, terminal, & connector)
TECH NOTES:
Over the years, the terminal, connector, and wire to the temperature sending unit may have been altered by a previous owner or mechanic. This was not uncommon. This alteration was most likely made in order to try different sending units when the "exact replacement" unit didn't work or was not available. After finding a sending unit that "worked", they would cut-off the original terminal & connector from their harness and splice-on the one that mated to their new sending unit.
With Lectric Limited's Temperature Sending Unit Lead Repair Kit you can repair or replace your temperature sending unit lead wire and get your wiring harness back to the way it originally looked and functioned.
This easy-to-install kit splices into your existing wiring harness. Heat shrink and harness tape are not included but may be required. Non-adhesive vinyl harness tape available separately. (See "Repair Components" section)

Subject: Anti-Theft Alarm System Interim Modifications
Several modifications to the 1977 Corvette anti-theft alarm system were introduced into production effective March 21, 1977 with VIN 1Z37X7S427373.
(2nd Design) modifications are as follows:
- The actuating switch for the alarm system is no longer located on the left (driver's side) front fender. It has been incorporated into the left front door lock and must be activated by locking this door with the key from the outside of the vehicle. This is the *ONLY* way the alarm can be set. Turning the inside knob to the locked position when exiting the vehicle *WILL NOT* activate the alarm system.
- The anti-theft alarm system horn has been moved from the left (driver's side) rear inner fender to the far left side (driver's side) of the engine compartment dash panel.
- The anti-theft alarm system flasher assembly is now located on the console trim plate, rather than the rear compartment underbody panel.
- The new anti-theft alarm system wiring diagram has been modified to reflect these changes.
