Yea I foolishly put the airflow pointing to the front as well, but now that I changed it out when I pulled the old one out the debris was on the side that is supposed to be the clean air coming out ofwhich is where the arrows are pointing to. So I had it backwards the whole time. I think the arrows are supposed to point towards the back of the vehicle
Correct, only Volvo filter has arrow for to represent orientation, not airflow. All aftermarket filters will have airflow arrow , which will face rear of vehicle (fan side).
i have yes. fuel relay is the black / pink wire behind the passenger headlight . ignition wires goes to 2 of the 4 wires behind the ignition switch/key
I have a s13 with the hexagarage universal wiring for a vq37. Those I dividual wires goes into your dash near the radio and will need to be wired in there. You'll have to pull a 240s wiring diagram to see which colors needs to be cut and connected to. Even foe the ground that has the connectors could just be cut off and ground to the chassic if you can't find the plugs for it which I doubt it. As for the fuse box in the engine bay. Just remove the battery cable, alternator, and whatever else is connected to it. And if you did have a battery cable and alternator/starter cable then they go onto your battery.
Take black tape and tape those relays up nice and tight to your harness, and those funny looking plugs are for ur o2 sensors what about the battery wires for your alternator and the little exciter wire?
