ka should be 6 in 6 out then 1 and 1. the neo is powered by ignition power, so when your key's off or in accessory it won't be on , when your car is running it'll be on. i just wired one in last night lol tell apexi WTF no knock sensor signal yet you give me a worthless illumination wire you don't even have to wire in.....

when your car won't rev past 3 grand it's the frickin maf. either you wired the safc2 yellow and white wires in backwards, or you didn't make it 6 in 6 out
