1990 GT convertible check engine light


Hi guys:
I am living in South Africa and brought my 1990 Mustang GT convertible over with me. The car had done 150,000 miles and my mechanic suggested I have the engine reconditioned. Six months later and a lot of money, it is running well but the check engine light is on most of the time. Nobody in this country including the agents can read the onboard computer codes.
Can I send the computer stateside? can I somehow read the codes myself with a laptop?

I have disconnected the negative battery connector to rest the the obc
but the light comes on again.

Stuck in the boondocks
