Today I picked up a ECU from an 87 MJ to swap into my 88, trying to get it to pass emissions. I asked the mechanic how long to install and he said "maybe" by the end of the day. I took it home, searched the forums, and found some hints. It took me awhile but I managed to do the swap. Those bracket bolts are a PIA to get to.
I also installed some JY finds. Glove box lid, hockey stick door handle, and parking light lens.
