    yea it was a lot of wiring. and a lot of circuit testing. that aem controller is expensive enough that you want to make darn sure everything is wired right before you plug it in, lol. after an entire summer of wiring, when i connected the battery, the only thing i had wrong was the relay in the underhood fuse block i re-assigned to be my vtec relay had the nc post still connected to a ground. and i had common as pwr and no as vtec solenoid, so whenever the vtec wasn't engaged it'd pop the fuse. out of everything i did that was the only problem. i mean i did go through a couple of alternators due to a output vs load issue at idle. but that was not the fault of my wiring. in the end i paid a chunk of money to an alternator repair shop and they got the 110 amp alternator up to 160 amps and got a smaller pulley for it so it can handle the +100 amps at idle my car can draw at times. the below picture is illustrating a 20 milliamp draw on the circuit I am testing. at 20ma this circuit/test could only be ignition off draw. and the draw is coming from the aem ems-4 and 250watt m4-atx dc-dc power supply I bought right here at mp3car.com.
