ECU smoking after swap install. NEED HELP FAST

Alright guys. Here is the car:

1993 Honda Civic CX
JDM Sir-II B16 swap
94 Civic EX harness

When we started the car with the chipped P28 ECU the ecu started smoking like a ****. We didn't know what was going on so we swapped in the stock CX ecu. Once again it also smoked.

We opened both the ECU's and the R135 was burnt on both of them.

What they hell do we do wrong? I really need help ASAP.

If both ecu's got smoked up then I would say you have a short down the wiring harness. Check all connections.

I think the wiring harness is good. We checked it.

My engine is also throwing an IAT code and VTEC solenoid code (VTEC isn't wired yet).

I read if you accidently have the IAS and PCS wires reversed it can fry some USDM ECUs.
