Help! Replacing single light switch with digital timer
I thought this would be an easy install but once again am wrong.
I pulled the single standard light switch circa 1985. There are 3 wires. 2 are black with no markings and the third is metal wire. One of each of the black wires go into top and bottom holes again with no labeling and the wire to the side connection.
The new timer has 4 connections; black/hot, white/neutral, green/ground and to make it more confusing a red wire.
Can I do this myself or am I going to need to bring out an electrician to replace a single fixture? Man, im bummed.
