I checked past posts and did not see this question, I have a 67 Elcamino and just bought a new console wiring harness, the plug for the clock is made with two plug connector but the back of the clock only has room for a one wire plug, is the clock missing something or did I get the wrong harness? Also at the plug to connect to the extension harness there is a single groung wire, where does that go? Thanks

Here's a pic showing the 66-67 console clock connections.

As I was snooping thru my chevelle assy manual (66), I noticed that there is a ground wire attatched to the front console bracket.
Actually a good spot if the bracket is welded to the floor.

Thanks, my clock is missing the + spade on the back, I ordered a quartz clock but wasn't sure how it was going to hook up, now I see, the previous owner had two console extension harness's hooked together and halfway hooked to the main harness, it took me awhile to figure that mess out and get it straight, now I am headed in the right direction. Thanks for the help and the pic!
