The module bolted to the bracket is electronic spark control. I think missing from the bracket is a barometric pressure sensor, might be what the blue connector goes to.
Anyone know where these plugs go?

The blue is TPS, note the slots cut at 12 o'clock position on both outside connectors. Not unless GM did some strange things, the MAP is a three prong weather pack connector, but slots cut/cast into it will be at 90 degrees and there will be one on the center connector, IIRC will be at the 12 o'clock position. Line up on the TPS connector is totally different.
would you happen to know the type of TPS module that fits onto that bracket over the tire well? Ive been looking in google but cant find anything that looks like it goes there. it could be an odd TPS module because this has all the wonky late model CA emissions BS most dont have.
Not a great pic but you can see the blue plug in the MAP or Barometric sensor on the passenger inner fender well.
A little more reading and it appears the VIN G 305 (California and high altitude) has a Barometric pressure sensor. The VIN H 305 (everywhere else) uses a MAP sensor.
Most MCs have a baro sensor. Vin G is theL69 HO V8 engine option in the SS sub models. Vin H is the non HO engine option.
Looks like maybe CA emissions did something different. Causing confusion. As long as connector snaps in and unit works without issue, good to go.
