loose wire in harness causing cut off...NEED HELP ASAP

[Goya20]

I was checkin my ecu if its chipped because as i stated on my last problem as i get on the throttle fully the car holds me back and i cant pass 95mph. I wanted to see if it was governed. i open the ecu and found a bmp design chip so i decided to close the ecu up bolt everything up and started the car closed my trunk and the car cut off on me. pushing the wires in a way causes it to start up but the bumps in the road can cause my car to cut off. Can something be loose in the connector to the ecu?

Pushing what wires? Since closing the trunk and bumps shut off the engine the first things I'd suspect would the main battery cables, the fusible link, the connections at the power point in the engine bay, and the DME grounds on the right shock tower.

The bunch of wires that run straight to the dme onto the black attachment that connects to it. Also I remembered there were two lil screws I didn't screw in into the dme. It consisted of 4 phillips head screws and the threaded adapters weren't lining up I'm thinkin one of those are touching something in the dme to cause it to start and not start. Imma check in the morning.

as i suspected it was the 2 lil screws i didnt put in guess it was needed to complete the circuit of the dme. still the car holds me back in 3rd thru 5th gear around 4000rpm
