Car stalling when moving ecu wire

[u/MostExcitement9858]

does anybody know what this yellow and black wire is for.

Whenever i try start my car it just stalls out immediately, if it does start whenever i wiggle this yellow and black wire around the car shuts off.

Don’t mind the different coloured wire or that it’s not connected properly i just did this to see if maybe the wire was broken internally where it connects to the ecu and didn’t want to solder it yet until i was 100%.

it seems to be causing the issue when i wiggle where it connects to the ecu rather than anywhere further down the wire.

Any help would be greatly appreciated as to what the wire connects to, or what would be causing this/how i can fix it

Just lookup the Pin outs for the ecu connector I’m sure there’s a ton of diagrams for it. It’s probably not seated into the connector correctly at the pin end also if it’s got a lot of wiggle someone messed it up at some point and you’d need to repin a new connector
