I need harness from 87/88 5.0 plus the computer if possible.
I am putting 408 into very nice 87 turbo coupe body.
I currently own 85 Elan with built 351, but not quite enough oomph.
Assuming this monster has a 351 firing order(13726548) you don't want a Tbird/Coug 5.0 computer, the '86-'88 are all speed densety and only support 14lb injectors. For maximum power, you'll need a '89-'93 Mass Air Stang EEC, 30 lb injectors, and matching air meter. For the harness a Bird 5.0 can be used, but will need to be converted for mass air operation. Even then it won't be a direct swap, as the body harness it has to mate up with is unique to The Turbo Coupes. You may want to look to the Stang for the harness as well...
if you choose to go with it i have both the computer and the harness sell both for $30+ shipping will split up too let me know
Thanks for the info I already did the mass air conversion on my current bird and would like NOT to have to repeat the exercize
