Console Gauges 1969 Z/28

So, I happen to be under the dash tracing some wires and noticed a harness for Console Gauges. My question is: Are gauge harness prewired from factory or is it safe to assume they are added only when U17 is optioned

The console and the console & gauges used different harnesses than the non-console harness.

So if I have a harness already underneath dash, does the mean car was console with gauges

If I have gauge harness underneath dash near radio, would that mean I had console with gauges

Just to clarify, the main dash harness (runs from firewall to glovebox area) was wired differently depending on the options.

If a console was optioned, the main harness received a large rectangular connector. Wires installed in connector were based on additional options.

Manual with console only received the wires for the ash tray light. Grey in color mostly.

Auto with console received the lights for the shift indicator, neutral safety, reverse lights and ashtray. Easy to see with the two large purple wires for neutral safety.

If console gauges were ordered with either of the above, then a lot more gauge wires were added (many colors). Plus tach & clock wires were added to the main harness.

So all you have to do is look at the number of wires and their colors to determine what you have.

I will take a few pictures tonight and post.

Take a Clear Photo of the Face (aka Pin Side) of the "Console Wiring Harnes Under Dash 12 pin-Connector" & we can decode the Pin out arrangement to tell VERY easily if the Harness was set up for D55 Console Only or D55 & U17 Console With Gages.

I’ll take another pic of face of harness

So, I can't see the wire colors in the rectangular connector the way you took that pic, we will wait for the new pic. Here is a post on Team Camaro showing the gauge wiring diagram:https://www.camaros.net/threads/wiri...gauges.467971/

Also the pic with the purple wire connector is for the clutch safety switch mounted on the pedal support.
