1977 Console wiring question
On a 77 Vette, the gauge cluster wiring harness. Which end goes up? It is numbered 1 thru 12. It appears that a orange wire and a blue wire on at the end off one side and a black wire and a grey wire on the other end. I appreciate any help. The harness was not connected when I got the car. I just don't want to damage anything hooking it up backwards. Thanks again!!!

I believe the big connector ffor the center gauge cluster (plugs in to the printed circuit on the back for fuel, temp, clock etc) is keyed so it only goes in one way on my 77.
My dash happens to be apart so I’ll post a picture when I get home.

Most GM connectors are made this way to avoid issues with plugging them up wrong.
We actually make that connector and I've posted a picture below.. .it's kind of hard to see the difference in the picture though. The guide barb on the connector visible in the picture below.
