93 chevy van remote start wiring

I bought a bull dog remote start/lock system and the color codes for my van are not the same as what they should be.  I don't know if they are aftermarket/replacement wires in the steering column or not.  Any help would be great.  I should have red, black, brown, yellow... wires and instead - I have pink, black, brown, green, yellow, white, orange with white stripe, purple, and light green.  I think that is all.  If you can help and need a picture or the order the are set in the column, let me know please!  Thanks.

That's what I was afraid of - the colors in the column are, in this order from left to right, white, green, yellow, purple, brown(constant power), blue, light blue, black, light green, orange, and grey.  I have tested most of the wires, but I am still confused as to which is which one.
