Ey guys,

I've been looking into what a few of the wires on the harness are for and I've been quite unable to figure it out.

Under the intake manifold below the egr where the starter wire is, there are two white/blue wires and 2 brown wires. I know that the whites ground out to the intake manifold but I'm not sure about the brown ones... They have a similar grounding ring on them.

Any help is appreciated.
