Help Needed With Reverse Lights

REVERSE lamp power on these cars originally was hooked to the wiper switch. The wiper switch receives UN fused power from the "in harness splice" coming from the ammeter circuit, and has a circuit breaker on or in the wiper switch. Wiring for your lights should be white (or violet/ white), power, and violet, cold side of switch to lights

Here's part of the '66 factory manual, which you should have. You can download it from "MyMopar:"

from here:

The page numbers in that manual do NOT follow conventional Mopar numbering. Diagrams are on pages approx. 305

Here are some excerpts from the 66 manual:

At the bottom of the wiper, B1 also feeds power off to the backup light switch. Wiring depends on whether it's stick (goes through bulkhead, to manual box) or console, so either wiring goes to colum switch or to console connector

In the drawing of the console connector, "3", (B1) is power to the switch, 1 (B2) is switched lamp power, which then goes to the kick panel connector for the rear harness

The same conector is shown in "console wiring" showing B1 and B2 C to the switch, B1A and B2D

The largest drawing shows a column mounted reverse switch, the dotted lines showing stick instead of auto wiring.
