That is a link to the Stewart Warner spec page for senders. It lists the senders according to gauge "capacity" not sure if they will work as this set is older, but you could call and talk to a tech there. I cannot imagine they have changed much though. The second one is the official site I believe to get tech numbers and so on.

aww that is one I haven't seen before. That would work I suppose on a sunpro gauge..no idea about a warner though.

I know your issues are solved but I was just snooping around an the part number of that sender from amazon has the wrong picture with it. The part number is Sunpro CP7577 which according to sunpro's website has a sender that looks like I described and would require that adapter to push the sender away from the block:



What they have pictured is the temperature sender.

Coolant Temperature

Fact: your only temperature feedback is the engine light whcih tends to come on after you are already overheating

replace the stock sensor found here, next the the alternator bracket brace, with the sensor that comes with the gauge (adapters will be needed, usually included)

(image shows a mechanical type sensor and tubing)

I am working on getting at the very least a temp gauge working before a long trip this week... I just looked in my Haynes manual and it says the sending unit for the gauge is on the intake manifold next to the distributor, but up above it mentions it being next to the alternator bracket. I believe there is one for the idiot light and one for the computer... I just want to be 100% certain I replace the right one. I meant to look for it today, but got sidetracked.

Thanks

Yeah there's two sensors for the coolant temperature like you said.

Mine is going off the one to the right of the distributor behind the alternator bracket. (Circled in red below). The other sensor used by the computer is circled in green.

Yep. Idiot light by alternator, computer by ac compressor.

Thank you Slack and 87gtVIC, I appreciate it!
Got the sending unit wire run and the rest of the electrical almost done before it got too dark and the skeeters came out.
