just installed mine on the 86 ,
not a fan of the box in stock location (its not potted against vibration). i put the 6 pack coil on the stock bracket and put the ign module where the cruise servo was so its easy to get to the dip switches in the pits
on a couple installs on ac deleted cars i put the ignition module box behind the glove box in the dash
as soon as i get around to it i want to switch it over to ls style coils
oh and you need to be careful on your installs with that braided line for the fuel gauge and the exposed post on back of the alternator
