325e M50 blower motor/ sunroof issue fix

[ian325is]

I put an m50 in my car about a month or 2 ago and afterwards my blower motor and sunroof wouldnt work. Tonight I spent some time staring at schematics and realized I never hooked up one of the wires. I thought I had done my research and did enough to make the car run and drive but after some tests with the multimeter it turns out I never hooked the ground up for the k5/k7 relays. Its a black and yellow wire going into c101 (dont know what pin as I made my own pigtail) and like i said it goes straight to ground. I installed it on a nut on the strut tower for the time being and everything is working great again. Im sure this is common info and if I would have taken more time or bought an adaptor this would have been a dead issue but just in case anyone is having these issues I figured I would throw this out.
