1969 Boss 429 Temperature

Is this general rule across the board including 289 and 302 engines?

Yes. It is the same sender.

With the way companies designate responsibility to some numb nuts lowest entry level engineer to spec it, I would caution everyone that even if Motorcraft for instance decided that there was enough of a market to remake them, I would not be shocked to find that they made them with the wrong  ohm rating as well.

You must realize that these companies are still run by MBA's who will tell you that an item like this is only worthy of a minute or so of their time and assign it to someone with little or no experience in getting it right the first time or aware of the pitfalls of using someone else's data.

You are still better off with an original IF you can find one. It will save you alot of grief, wasted time and energy.

In 69/70 the GT350 got a green insulator version.

It is interesting to me how knowledge is so easily lost even with a small passage of time.

I've seen the green one called an F150 sensor.

I have notes from 10 years ago that the Echlin TS6628 will bring the temperature gauge back into range.  I know I installed one with success on my SCJ car.

Here is the Echlin TS6628 at Napa

Negative on this. It apparently was revised as well. That was the first one I tried. I thought I blew the engine. Just an inaccurate sender.

Nope. ORIGINAL AUTOLITE OR MOTORCRAFT ONLY.

One of my aftermarkets was from NAPA but I do not know the part number but I suggest verifying your actual temp against the gauge if in doubt. I just got puzzled again after reading Mr Gaines comment because my 69 GT350 4 speed convertible with factory air, which is supposed to be restored to near factory specs, has a black insulator. Gauge works accurate. Two local old time mechanics and myself learned a new one on this project. We were all ready to call Doug on it :-) Once again better to listen and learn before I speak.

You found an aftermarket that works?  Share it...but...

Sorry, None of my after markets worked, including my NAPA. Doug was 100% correct. Me and my mechanics just doubted him  . I was lucky enough to finally find an OEM from someone and it worked..

59.00 is a fair price for a service replacement Motorcraft sender.  The Autolite marked versions typically sell for well over 100.00 each.
