Hello and welcome to JustAnswer!

If you're referring to the connectors I believe you are there is no current running through any of the circuits. The yellow connectors are for airbag components and the only time current would be present is for a fraction of a second during airbag deployment.

What needs to be done is a proper ignition off draw test to see what fused circuit the draw is on. Has this been done?
