Never hooked up. I had the box and instruction manual up until a couple months ago. Now I can't find them and suppose they left with some trash while I was cleaning the garage a little. Anyway, here it is. A true blast from the past. Period correct for the older cars like we have. Get it off my shelf. $20 delivered to the lower 48. Other places higher. First "I'll take it" gets it as it is listed on multiple sites. Thanks for checking it out.
