as to the harness, i can say that a 92 bonne firewall harness is the same as my 92 p/a. but im not certain if the 97s would be. i would assume so, but you know what they say about assuming.
and thats where i get confused about the p/a being a g body. cuz i thought the aurora and Rivieras were g bodies. and the p/a still c body.
PA became a G-body in 97. LeSabre and Bonnie got the same platform in 2000, but kept the H-body designation and the H in the VIN. Basically, same suspension, slightly different engine mounts, PA is slightly longer both in wheelbase and overall.
Anyway, the PAU shares the L67 and 4T65E-HD, no difference there, but the body, subframe, mounts, and suspension are completely incompatible. Axles might be the same, IDK. I believe your 97SSEi PCM will run it just fine, but I'm not sure if the engine harness is plug-n-play.
There may be small differences up top, because the PAU never had a boost gauge.
The subframe, mounts, axles, shocks, etc., should be easily obtainable from a JY.
