Gauge wiring

[Swedchevy67]

I will use my original dashboard and wounder if my 22 circuit wiring kit 910-64022 from Speedway can be conected with this part?

It can be wired up just fine. I'm not sure if your aftermarket kit will have all the sender wires but here's the diagram.

That's good news!
Thank you for posting this diagram.
There is only one catch: my number 5 was empty.

Your number 5 is for the temperature sender wire for the three gauge lights dash, on the seven gauge dash it was moved to the number six for the temperature gauge and the number 5 was left empty.

I used that very same wiring harness when I built my 71'.
Just be sure to add a ground wire from the chassis to the metal tin
Of the gauge cluster and to the bottom terminal of the temperature gauge
(Ask me how I know) I kept thinking I over torqued the nuts on the back of the gauge where the circuit board attaches, causing the circuit traces to ground against the tin, turns out,
it just needed a dedicated ground wire to read correctly.

I actually used the original front light harness and the firewall connectors, and terminated them to the speedway harness. Everything was labeled so it was simple, just verified the factory wiring diagrams to the speedway schematic and was super easy.
Have a good one!

Yep, additional ground is always a good idea. I added one to the tin of
My cluster and used a bullet connector for easy removal.

I don't follow "terminal of the temperature gauge".
It's hard to understand the technical language in English up here in northern Scandinavia.
Can't I use empty nr 5.

Use the Electrical Section in the forum. VV is a great asset here and is always helping someone out!

Suprised this has not moved to the electric forum yet!

Don't feel bad I can't speak a darn word of Swedish.

Let me make it easy for you.

The no. 5 goes to a light socket for a warning light, the gauge dashes don't have a warning light.

They moved the sending unit wire to spot 6 and left 5 empty. See dashed red line on diagram.

The copper strip for spot 6 goes to the temperature gauge post (terminal).
The other post (terminal) gets 12 volts from the fuel gauge post .





the temperature gauge with the terminals (posts) labeled.




Känner mig inte dåligt Jag kan inte prata ett darnord av svenska.

Låt mig göra det enkelt för dig.

Nejet. 5 går till ett ljusuttag för ett varningsljus, har mätinstrumentet ingen varningslampa.

De flyttade sändningsenhetstråden till punkt 6 och lämnade 5 tomma. Se streckad röd linje på diagram.

Kopparremsan för punkt 6 går till temperaturmätarens stolpe (terminal).
Den andra posten (terminal) får 12 volt från bränslemätarens stolpe.

Not bad!
