JS - - Maybe you oughta try the '95 ECU in the '97 just for the heck of it.
I just had the head off and on reassembly looked at CPS wiring for another poster on here.
I'd be darn sure before I invested the bucks myself. But once you have your new one in hand, it enters the block down low below driver side front of head, I think it's a 10mm headed M6 bolt that holds a tab and the barrel of the CPS is sealed with an o-ring. Wiggle it back and forth while tugging and it will come out.
Then a strap at left front corner of block. Around back it gets kind of messy. The jacketed pair of wires runs under the intake manifold and is clipped to the top of the heater pipe that runs along there and around the end of the block to the water pump. Then just behind the alternator it plugs into the harness, one of those with a stainless wire spring clip like the injectors and the MAP sensor.
I'd just leave the old one dangling and try the new one first, pass it thru under the intake and plug it in.
If that cures things, then I'd be tempted to leave most of the old wires in place, zip tie the new one to the old one near its plug and nip the old plug off, zip tie the new one to the old just as it dives in under the intake and nip off the old sensor and some of the wire.
If you like things factory and want to deal with those clips, one is directly under the gap between intake runner 1 and intake runner 2, and the other is directly under the gap between intake runner 3 and intake runner 4.
I would see if flat on my back under the car I could get a light up in to see them, then poke them from below with a long screwdriver and they should pop off. You'd have to get an arm in from one end or the other to re-clip them; I had the alternator off after I put the intake back on and I was able to reach in from that end and find them both.
They're like the clips that hold the oxy sensor wire to the top of that same pipe behind the serpentine belt. About half an inch wide, shaped like an oval with one side missing and a little lip bent out at 90 degrees, from where they can be released.
