I bought my e92 from PO lowered without a passenger fender liner and outside temp at -40.. i noticed the wires and i tried splicing what ever i found that matched..i got the fog light to work but i have 4 wires left a blue-red & blue-brown from the ambient air temp sensor and purple-red & a brown wire from
The horn... but the wires remaining dont all match.. i habe the blue-brown wire and i have purple and red wire but the other 2 wires are brown-white and black-white... i traced the wiring and unwrapped most of it to see if theres any broken connections hiding and there isnt any one got a clue?
