Facts about the original 1977 Delay Timer
Extensive research has determined that the original 1977 delay timer charged a capacitor inside the module. This meant the delay light time was different than the later 1978-1982 and 1984-1989 cars. The amount of time the timer stayed on was determined by how long you had the door open (to a max). We have tried to get as close to the “mean†to what is/should be considered an acceptable delay.
Another unusual factor with the 77 delay timer was that unlike the 1978 and later cars, when you turned on the ignition switch key the lamp did not turn off. The cars built after 1977 with delay timers would turn off the interior lamps when you turned the ignition key on. 1977 cars depended on the capacitor bleeding off regardless of whether the key was turned on or not to turn out the lamps. The amount of delay was determined by how long the doors were open and how long the capacitor was charged.
To replace the timer you are required to remove the left hand dash pad.
This product is only designed for cars that already have the delay timer option ZX2, and out of the 49,213 cars produced in 1977, 40,872 of them came with this option. If you do not have this option, do not purchase this item. While all cars had a jump connector (male and female) right on top of the main dash harness, this kit doesn’t come with the jumper harness to install it on a car without this option. Should you decide to add this option to a car you'll need to contact sales for the appropriate part number for the original jumper harness. If you don't have this option in the car you simply unplug the wires behind the dash, and then install the jumper harness, then run your ground and your set. As stated above this module is only made for cars that already have this option.
The original timer was a metal can design, and when purchased over the counter, it came with the jumper harness to add this option to any car. Our timer won’t come with this jumper harness, and this is why we say this is only for a car with the existing ZX2 option.
