I did that first ; ;i called cust service ; in irvine ca. they gave me # for my state [tempe az]

the distributor/dealer was no help ; he said that they were hot. and that since i am not a dealer that he would NOT help me at all.; so thats how I came to this site . and am very glad that i did.

black - ground

brown - (-) door trigger

purple - (+) door trigger

white - parking lights

WHITE/ black - siren output (+)

BLACK/ white - horn output (-)

dark green - trunk trigger (-)

GREEN / WHITE - dome light turn on lead

RED / white - parking light polarity (usually leave connected to red constant wire

2040 is the same but the blue wire is a negative aux wire
