86-87 and 88-89 LX-i parts differences

After searching high and low for an EGR valve for my 86 LX-i, I finally resorted to purchasing one for an 88 model. It appeared to be the same valve with a different connector. Unlike the correct valve for my car, it is still in production as it also fits 4th Gen cars.

Well guess what? I've run into the same issue with my throttle angle sensor. (I'll refer to it as TPS). I cannot find any listing for an 86 Accord TPS sensor period, but I have found several TPS sensors on eBay that claim to work on Accord/Civic/CRX/Prelude from 88-up.

So this leads me to my question: will an 88-89 TPS work on an 86 throttle body as long as the signal, 5v ref, and ground are all hooked up the same as I did with my EGR valve position sensor?

Are there other components that would also work from the 88-89 cars? To be clear I'm not really wanting to modify anything I don't have to. I'm simply trying to figure out the best and easiest way to keep this car functioning as it's supposed to as it and I go through the pains of getting an almost 40 year old car back on the road after a long period of sitting (10+ years).

I don't see why the TPS wouldn't work if you just need to repin it

I tend to think it would work, though I'll need a connector pigtail for the 88-up as the 86-87 style has a pigtail as part of the sensor and the 88-up doesn't.

He tenido problemas acá en Chile para conseguir repuestos para mi Accord LXi 88, en el caso del MAP, que tiene 3 pines, en teorÃa deberÃa servir casi cualquiera, toda vez que sólo se necesita comunicación a la ECU, con 3 lÃneas (+5V; GND y Señal), lo que hay que adaptar es la ubicación de la lÃnea de vacÃo, y su instalación fÃsica por la diferencia de las perforaciones para sus pernos de sujeción.
