SRS Unit Interchangeability

SRS Unit Interchangeability
My SRS light has been on for as long as I've owned my car. At first it was a 5-2, I replaced the unit with one from ebay. The code switched to a 1-3, I changed the drivers airbag and nothing happened. I suspect the unit I got on ebay wasn't good.
I have a bunch of SRS units from the junk yard but none of them match my exact unit. The plug, however, is the same.
Question is... Should I attempt to plug in one of the other units?!?
My original unit was a 77960-SV4-308
One replacement is a 77960-SV4-A90
The other is a 77960-SV4-A92

Car-part.com shows only the 1995 as a donor. Check ebay which also has a cross-reference system but pretty flaky IMV. Anything but a 1996 or 1997 would be unlikely to work. I don't know any way to be sure.

SRS units have to be changed "like for like" your original one is a "DE" manufactured one. There is a service bulletin on these as well. And besides all that, using a junkyard SRS unit is not the best idea either... my .02

that's the problem, Honda doesn't make'm, they used 3 different manuf. DE, Takata and NEC.

The original was Densigiken and the replacement was NEC.
Now for the interesting part... I just swapped the 77960-SV4-A92 for another 77960-SV4-A92 that I had (also junk yard). The light is now off... interesting, no?

this might just be me, but i won't use parts for safety systems that may have been compromised...the impact sensor for this system is contained withing that SRS unit and if it is damaged in anyway the bags may not go off or go off the next big bump you hit...BMW's had a similar problem with their modules.
