This is what I would do. I would try and get a harness from either an 87-88 Turbo Coupe T-bird, 87-88 XR7 Cougar.
There are plenty around, and you can always swap to a turbo if you want. The 2.3l block is VERY stout, and will handle many ponies. Also if you can get the engine along with the wiring harness from the Ford/Mercury's above they came stock with forged pistons.
