switching wires from 89 into 88

[Late]

So as the title says, im switching all the wires i have to into my 88 shell from my 89, what i would like to find out is what of which i have to actually change?

From looking it appears that the doors have the same plugs so i think those can stay, but do i have to switch the fuse box area where all the wires plug in or is it the same from 88-89? i feel like im going to run into issues when i change over the dash wires if they dont match up.

my 89 is complete and was running good with all electronics working so i know the wires are all good, before i rolled it.

if youre wondering why i dont just keep the wires that are in there now in, most of them are cut and randomly split and i would rather have my nice non-cut up wires that work fine in it. also do not have an 88 harness.

thanks

well i decided to look at where the wires plug in on my 88 shell(dont know if i call it fuse box or what) and im assuming all the yellow ones would have to be grey to work, looks like im switching everything unless somebody has any insight.

i already have all the wires along the sides out and what not, just have to get the ones close to the firewall out
