I am going to be swapping everything that is usable from an 88 L-98 Formula onto my 84 lG4 trans am. how different is the wiring setup for these 2 cars? Most likely I will be replacing every wire on the 84 with harnesses from the 88. So, please explain any differences in wiring such as the dash, taillight, and other body wiring(windows, etc.) Anyone whos done a swap like this, please give me all the helpful pointers you can. Thanks in advance.
