Stock 07 Si sedan. Critters chewed my harness that comes out at the end of the injectors. It feeds the oil pressure switch, vtec solenoid ( one that goes into the front of cylinder head) and crank sensor. All wires match up to the respective plugs except one. It's yellow with a red tracer. When ground is applied to this wire the low oil pressure idiot light comes on. Which wire does it piggyback to or does it go somewhere else? Wanna get it back running. Been down for 2 weeks now and can't find or trust just general Google pics. TIA.
That should go to the oil pressure switch located around that same area. Block is upside down in the pic. This is the backside of the block on the passenger side.

I understand what it does, just need to know which wire it piggyback off of. There are 2 wires going to the switch. Which one does it share with?
Can you post some pics? I don't understand what you mean.
That pressure switch should have one wire going to it. The sensor itself is grounded through the block. When oil pressure is low the switch closes applying that ground to your yellow/red wire. Are you saying you have the wire on the sensor side but don't know where it goes on the harness side?
