Ms3x no 5vref I think
 

Hi everyone, new to pretty much everything here, but I need help. I got an ms3x built buy diyautotune and built an adapter harness to the stock ecu connectors on my 99 1.8 miaduh. I dont have the test rig to check all connections, so I have my ecu in my car. The ecu just isnt powering on, and I dont know why. I have checked all of my connections, they are all solid connections with no resistance or anything. I built my harness per a pinout I found on here, that i'll attach. Really lost here, any help would be great. Also I am going to be running an aem eugo on my otherwise bone stock miat if that changes anything.
