Greetings, 

 

 

Im reaching out to the Subie community for some help. I just completed a head gasket job and i am working on final re-assembly. I thought i did a decent job on the repairs and putting things back where they need to go, but alas, i have two ground wires (i think) i failed to label. One is a black wire coming out of the firewall in front of the drivers side and the other is a hefty black and yellow wire coming out of the wiring harness that connect to my battery (see photos 2/3). I believe they both attach to the intake manifold above cylinder 4 (upper right from bird eye of engine bay, see photo 4). However i also noticed another threaded hole on the block (photo 1) that is within reach of ground wire coming out of firewall. Does anyone know where these go?

The big one looks like the starter ground. The other one, I don't know. It looks familiar though, I remember that bracket. I'll check under the hood of my car when I get home tonight.

The large black/yellow is your main battey ground. It should be attached to the same bracket as the other wire in the pic. That bracket goes on the upper starter mount bolt.
