Trying to get all of the low fluid sensing circuits functioning again on my 88 GT. The low coolant sensor assembly is all corroded and needs replacement. Replacements appear to be discontinued and I’m unable to locate any NOS. Has anyone successfully retrofitted the 90+ sensor (still available) and if so, will I require a different overflow bottle as well? I’m sure I will need the 3 wire pigtail, and sensor but not sure if anything else is required. Thanks in advance for responses. Please stay safe!!!

I replaced 2 or 3 of them in the first 5 years I owned the car. It's really unnecessary.

You need the 3-wire sensor, sensor harness, and bottle. The above link can show how to rewrite it.
