I sent my ECM for repair and they found it wasn't repairable, so I got a replacement. The car starts right up with new ECM, so that's great, but in the long time waiting for the ECM I forgot how it mounts. I also believe that the replacement has the wrong mounting lugs, having two pins on end and old one appears to have four threaded lugs on the sides.

I also am baffled as to where a couple of connectors under dash by ECM connect - if they do.

Any assistance would be appreciated!

Thank you! That reminded me and I found the clever place I stored the mount. I also see where the wires go.

Thank you so much!

 

Btw the other wire look like the hook to the Vss buffer on the ecm bracket
