Default 1993 Mustang 5.0L swap- Wiring harness from 1989, fit with dash harness?

Relevant info-

1994 5.0L GT Donor car- owner wrapped it around a tree, I bought it from him and pulled the motor and transmission

1989 5.0L GT Donor car- I wrecked this one- pulling the EEC/EFI harness, Distributor, rear end

1993 2.3L LX for the swap- so far have the entire front/rear suspension from the 94 swapped into it. Car has complete dynomat sound insulation, and currently has the 94 5.0 engine sitting between the fenders.

My question- I have the ECU, EEC harness, and EFI harness from the 89, which I will be using with the 89 MAF sensor and 89 distributor. This *should* wire up the engine just fine. My problem is hooking it up to the 93 dash. Anyone have any input here? Will it be plug and play- if I can find the correct wire diagrams to spice the harness?

I have searched and found that the dash and eec harnesses are not the same, however am wondering what exactly I can do to get the car running.


The headers and starter should go into the car today, then I will be swapping on the 89 distributor tomorrow if it doesn't snow.

Any help with this would be greatly appreciated.

I know I can probably just grab the 89 dash harness, but if anyone have any other ideas, that would be great.

Thanks!
Max

Any suggestions?

The 93 has a grey round plug, green rectangle plug, and the 60 pin on the computer side, whereas my 89 EEC harness does not have the grey round plug. Anyone know what its for? Thanks!
