After I did my swap everything worked great, now two weeks later I wired the vtec and my battery is draining when my car is not running. I bought a new battery, mine was 6 years old, took off the alternator and got it checked, worked perfect, now what? Is there anyway that my vtec wiring could be draing my battery? For reference I did a simple swap of putting a b18c1 into my 97 ls integra. Also was the vtec already wired in my car? I wired 4 wires, knock sensor, vtec seliond, vtec pressue switch, and secondary intake. I am not good with electric stuff. Please help me.
