hello I hope someone can help. I'm installing a 90 harness in to a 91 and i changed the plug for the ignition to fit one of the 91. Long story short I have everything is place and after I start it and shutting it off. My ecu started smoking and the mpi relay was not stop buzzing. I narrowed it down to c-60 ecu harness. But from there I'm lost. I keep reading the write up 19eclipse90 did but can find my answer. Any help would be awesome thank you. When it was running it can fine.
