Temp sensor wiring for '61 GMC

[5Tractorguy]

Does anyone have a wiring schematic for the 60-63 GMC's? I'm trying to figure out the wiring for the temp sensor on my '61 GMC with 351V6. It has two sensors on the manifold, one with a dark green wire that runs back into the harness and one white with a red stripe that someone removed and coiled up around the radiator hose.

Would like to be able to get the gauge working again if possible...

My schematic shows the dark green as the wire for the temp gauge. I have not found a White w/ Red Stripe. My 61 does not have that extra sensor on the lower left of the cross overhousing in your photo.

Ok I just looked at your video link and saw you have a 5000 series.

According to my schematic, there was a Dark Green/White stripe that would go to a warning light; if you had the Dual cluster.

I see you have the single cluster; but the third photo below shows the red Temperature warning light (HOT ENG)
that I think the wire is supposed to connect to.

Thanks for the help MM. I'll have to check the gauge and sensor and see if everything is hooked up/working. I don't remember off hand what I had for warning lights in the dash, I would assume since the extra sensor is there it must have a temp light.

if you had a temperature sensor on your truck the wiring would go to a computer. a sending unit which is what you have goes directly to the guage
