Hi Group I have a 1993 Civic DX auto Instrument panel and just up graded it with the tac one. On the instrument panel on the back there are 5 plugs that can go on to it, a long plug, a shorter plug, a yellow plug at the bottom and a green one at the bottom and a green plug at the top. The wiring in my car is missing the green plug at the bottom, but when I plugged every thing in , every thing seems to work. I`m asking if any one knows what this bottom plug , ( if I had it ) would power what? This is also a Canadian KL/M Speedo Please help.

 

The smaller green plug at the bottom is for cruise control.

 

Thanks so much for the info And Thank goodness we do not have cruse control on this car. I thought every thing worked right and it does
