Hello, all. Over the past couple of months, I've been installing a 1993 5.0 engine in my 1966 convertible. I've got it in and about ready to start it up but I am having a quirky issue with the 66 wiring. I've got all of the lights, internal and external, working as advertised, but when I activate the directional signals, either one, all four directional lights flash. The emergency flasher operates properly, also. I've gone through the steering column wiring and can find nothing amiss. I DID remove the steering column during the engine exchange but I did not make any changes to that wiring. I was hoping that someone out there might have experienced this issue and might point me int he right direction to fix it. Any help would be appreciated.
