Wires for instruments. I'm an idiot. PLEASE help!
 

I REALLY need someones help right now.

I need to start my engine after my renovation, this weekend. Everything is perfect, except my small and large combination instrument.

I'm not sure how to connect the wires, because I forgot to mark them when I took them out (big idiot... I know).

I'm using three diagrams to be sure to do it right, but i'm still not sure...

Can you see theese pictures and tell me if i'm doing it right or wrong? :confused:

Thanks guys!

What car? Year?
Pics don't look like the green 71 t.

It WAS a green '71.

Now it's light ivory '71.

:p

From a Green(!) '71:

Small instrument-
Solid Green -> Fuel
Green/Grey -> Oil

Large instrument-
Green/Red -> Oil Pressure
Green/Black -> Oil Temp

Thanks Jim, but I can see that from the diagram. I need to know wich connection points i have to use behind the instruments.

OK - pulled my gauges out and....

For your large instrument, it compares with mine except for the top (12 o'clock) connections I have a black with white stripe and a brown with grey dot. Below that I have a single black with green stripe.

For the small instrument, starting at 12 o'clock I have a black with blue stripe with a double ground directly below it. To the right of that is the double red/black like yours. Next clockwise I have a solid green, again like yours. Next clockwise is the large fitting and I have a double male spade with a black wire plus the red/black jumpered to it. Immediately to its left I have an empty male spade connector where you show your black wire. Again clockwise the red/black followed by the green/grey like yours.

Sorry for the text description - tried to get photos but couldn't get the camera to make a decent closeup. Hopefully it helps.

You made an error with the small combi instrument:
- the black wire should not be used a ground (only the brown)
- you used the instrument lighting bulb where the warning light for the fuel level should go. This light is connected to a red/black and the black wire

Does the gauge fry if the wires are wrong, I might have a similar concern on one of my gauges from a 77 911. I haven't put power to it yet. I did make a diagram but one still seems iffy!

Uh! Thanks man!

I will correct it tomorrow:)
