Side Marker Light Question
There are 2 hot wires to a 1157 park/turn bulb. A 194 bulb has only 1 element, thus only 1 hot wire. The question here was how to get both park and turn from the single element bulb. ( those hood mounted indicators don't work with the park circuit )
I'm going to add a drawing here... and I know that some will say this can't possibly work because its too damn simple. It does work though. This is how GM did it in several million vehicles.
If you do this, someday later down the road, a turn indicator in the dash will come on with the park lamps. That will indicate loss of ground path. Most likely that side marker bulb needs to be replaced.
