Hello folks just wondering if you guys can help me solve this problem, I purchased this "performance module" from Next Level Performance off E-bay, it sounded good at the begining but now I'm having second thoughts, on the MC (T-MAP) sensor plug, there are 4 wires labeled A-D on B and C, I found 5+ Volts DC according to the instructions that is what 'm looking for, which one is the IAT signal wire? I'm supposed to splice into that one to hook this up. sorry about the pics but my camera is not good quality. On the plug to the T-map there are 4 wires the 2 in the center B & C will give 5+ DC, I have spliced into both, when I spliced into the Red one the car just backfires and under loads it bogs down to the point where it goes into the safe mode where the car just looses almost all power it feels like the engine has some kind of brake on. When I spliced into what it looks like yellow with a green stripe wire the car works fine but I don't see any changes at all. I have attempted to get tech support from the manufacturer and seller several times but I have not received any. I have attached the installation diagram for your reference, it's simple, but without knowing for sure which wire is the IAT signal is hard to determine if the module is installed correctly. Thanks
