88 gt Motor Swap Issues. Need Advice.

[Thgzfrlife]

I bought an 88 gt a few weeks ago and found it had a blown headgasket. I decided to pull the motor and buy another one. Vound one on craigslist advertised as a 90 mustang 302 with gt40 heads and had been cammed. Turns out, it is actually an F-150 5.0 engine. I already have it in the car but I have no idea how to wire this engine, vacuums etc. I have been told before that I can use the original 88 gt engine harness, but it doesnt fit. I also have no clue how to run the mass air adaptor through the firewall.

All in all I think ( though I am probably mistaken) I have 2 options.

Option A: Hope someone has a wiring diagram or has a way to explain how this wiring extravaganza would work.

Option B: I dont even know if this is possible, however I was thinking about saying goodbye to all of the wiring and putting on a carb.

Possible Option C: Take off the heads, the supposed cam and put them on the old block and spend even more money on gaskets etc.

Any and all help would be greatly appreciated. After 2 weeks of working on this thing and 4000 dollars of saved up money I dont want to trash this thing and call it quits.

Whyd you end up buying a new engine over a blown headgasket? Wouldve been much cheaper and easier to just replace the head gasket. Howd you determine its an F150 engine? If its a HO engine, it doesnt really matter what it is from.
Did you just buy a MAF adaptor or an entire MAF harness? Switching to MAF you would need a new.computer as well. You should be able to use the 88 harness, just ditch the MAF. Might not run well depending on the cam though.

Switching to carb would be a pain in the ass because youd have to change the.entire fuel system.

Honestly what I would do is sell the engine and try to recover your money on that and just do the headgaskets, since the engine is already out of the car it should be cake.

I bought the MAF adaptor not the full harness, and I also bought the A9L computer.
