I won't try to explain everything here sp you can read my other posts below or try to understand my summary lol. I wired my ignition and starter solenoid wires from my key switch just to tune the engine, now its time for a long term fix, my question is that I was told between the driver side strut tower and the firewall there are wires which I could splice into, one is black with a white strip which would go to my starter solenoid and anothother which I could connect to my coil for the ignition. My problems are that there are two wires which are black with a white stripe behind the driver side strut tower, and that I have no idea which wire I could use for ignition any help would be great, and feel free to flame lol
