I have a turn signal and emergency flasher problem. I have been reading through my Osborne manuals and the 1967 mustang, cougar and fairlane service manual as well as trying to jumper and continuity the problem. In the diag section of the service manual, I see what appears to be very similar to what I am experiencing in the turn signals and emergency flasher. I have ordered from NPD the only flasher assy listed for 1967. It seems to be a combo flasher for turn signals and emergency. Despite the fact that the electrical diagrams list them separately in the service manuals. Are they one and the same on a 1967? Secondly, the diag section of the service manual says that I may have 2 wires crossed at the 4 wire 'turn signal indicator relay' or may need a new one. This can't be the same part that I ordered from NPD as I believe the NPD is a 2 wire flasher? The NPD pics don't show the back. Is there a " turn signal indicator relay"? EBay shows an NOS C7WB-13A366-A that doesn't look anything like the NPD one. Thanks.
