I thought this was going to be an easy install -- and it still may be - but I am feeling stupid. So before I make a mistake and leave a hole in my dash, I thought I'd reach out for some help. I have a 77 Dodge Aspen R/T - the car did not come with a clock. It has that blocking piece where the clock would go (the plate is all messed up from a previous owner). I was able to get a Digital Clock from a 79 Plymouth Volare in the junkyard. It looked like a simple remove the block and plug in the clock but to my surprise, the block is fixed in place, not screwed in like the clock. It looks as though if I "snap off" the plate, the clock would screw into place as the mounting holes are in the same location as the clock mounting bracket. Before I remove the block plate, I was looking at how to connect the clock. The unused harness in MY car is a 2 wire clip with a red wire and an orange wire. The harness which is with the clock (I got both connectors male and female when I picked it) has 5 wires. There is a red, an orange, a yellow/black, a grey and a black on both male and female. I was thinking color to color but then what were the other 3 wires for? Do the yellow/black, grey, and the black wire get ignored or do I need to connect them somewhere else?
