I am wondering why my inner marker lights flash at the same time as my outer turn signals on my 1986 SVO ? My son has an 84 and so did I years ago and neither did this. My inner marker light socket has three wires and his has two. I don’t know if Ford changed this for 86 or if I possibly have the wrong harness attached for the lights? Does anyone else have this issue? Your reply would be appreciated. Thanks, Calvin.
