There is a very low percentage of mind readers on this site.
Due to the current pandemic and political conditions of the country, (and for that matter, the whole world) the mind readers, who are a members of this site, are currently busy working on the thinking of the current Commander in Chief.
Thusly, it would be helpful if you could give us a few more hints as the history, condition, past problems and the future hopes and dreams of the car in question.
Fortunately, I am one of those few mind readers on this site. I am now sitting in a Lotus position, humming...hummmmmmmmmm, hummmmmmmmmm, hummmmmmmmmmm....
Viola! I got it figured out...today's weather is sunny, with a chance of showers.
How about posting some pics of the wiring or a video of what is happening so we can help you more.
