1 Wire to 3 Wire Oil Pressure Switch / Sender?

My 88 5.0 IROC came with the single wire oil pressure sender, and the 2 wire oil pressure/fuel pump power switch. Is there any reason why I can not install the combined oil pressure switch / sender (OPS) from later Camaros (89 & up or LT-1) and have it function properly?

I already have a 3 wire pigtail that I can splice in but I'm not 100 percent sure the ohm values are the same for the two different style oil pressure senders.

It will work just fine, one of the things I do all the time.
