So I just came across this gem on a bmw forum.
Of particular note are sensors number MT1297 and MT1339. They use the same connector and have nearly the same voltage readings but one is female 3/8-24.....same as a female Vintage Air trinary switch. VA has adapters to install that into a drier or inline fitting if you want.
MT1297 transfers to a GM 22599559 or ACDelco 15-72104 and it seems to have the same pressure/voltage ramp as the one parsons outlined about 4 pages back.
****Edit**** ACdelco 15-72104 does not fit the Vintage Air adapters. Thread and pitch are wrong so that is out.....back to the previous plan.
