This vehicle is a 2010 Ford Fusion Hybrid I have the system installed but I'm getting current backfeed causing issues until I unplug the T-harness then it all goes back to normal?? Unwrapped t harness and found that it already has the 2 diodes as per the tech sheet!! Only wires I connected were the 2 can wires the Orange wire to ground to disarm factory security in car and the driver door pin in the sjb harness pictured on the tech sheet it actually worked to a point once but then things started going weird due to current backfeed as soon as I took the t harness out and plugged the ignition harness into it's switch and the PATS harness into its switch everything went back to normal!! So it's definitely a backfeed issue somewhere running through the EVO??? This is a hybrid not the normal fusion any and all help would be greatly appreciated!!!
