I have had turn signals (from Time To Time) Since I bought my 1975 Bronco. The wiring in the back is a mess. Periodically, I have had turn signals for no apparent reason during this time. I put new flashers in it right after purchase. Didn't fix it. Then one day without me doing anything, They started working. However at this time, I had no brake lights and only one running light. Today I bought the new stop light switch and after fixing some shorts on poorly tied together wire in the back, I have brake lights and both running lights on the rear. (No marker lights or tag light yet). However, I still have no turn signals. Up until last week I could hear the blinkers clicking when I turned them on in either direction. Now its back to nothing. I tightened up both brown wires going for the running lights, and am left with 3 wires. There are plenty of little connectors with one wire coming in and 2 going out. These are where I have open wire. On the RH Stop and Turn signal lamp feed I have a green wire coming into a connector and two going out. One is connected to the left side light socket and the other is broke off danglingwith no voltage. On the other 2 connectors, one looks black or brown and has 12 volts on it. The other is a green and yellow it looks like with no voltage. This thing has had a healthy dose of undercoat some time in the past and they got the wires extra good. Short of the new rearend harness, any ideas? Also I have nothing in the front for turn signals either. And here while back they were working and I tried the flashers, and it made them quit again. Honestly I don't think they have worked since then.
