swapping interior and harness .. ID these

[1slo5ohh]

Swapping my black interior and complete harness from my 90 to my 89. The car wont have ac, heat, or radio anymore since its just a weekend toy so if i can get rid of some wiring it would be great and a little less crazy in there lol.

blue box behind where the radio and ac/heating controls would be

white box with 2 relays attached to it and a plug
View attachment 251496

blue box above/around where the glove box would be

any insight would be great, like i said anything i can get rid of to clear stuff up would be great.

I beleive it's mostly airbag stuff, but I am not sure.

First blue box is the "Air Bag Control Module"
The second set of 3 are the "Courtesy Dinger", and the "Horn Relay", And the "Day/Night Illumination Relay"
The third blue box i am not sure. Use the Numbers on it, and Google them, what the part is normally comes up.
I would like to know for farther reference too

Oh wanted to add, there are a few differences between the 89 and the 90 when it comes to wireing.
Youll need a few things, just one is the Turn Signal Switch/Handle, I believe the ECU and Ignition, and engine harness connections are different as well.
You may know this, just giveing a heads up.
