Installation of speaker crossovers for 2004 Lesabre

[realjohnkramer]

Hello, I have recently installed upgrade speakers in my 2004 Buick Lesabre and initially neglected installing the crossovers. This caused a popping sound in the door tweeters at medium to high volume. Upon attempting to double back and install them, I encountered a roadblock. I do not know which is the input wire(s) for the left hand door module that I would wire into the crossover. Secondly, I don’t really know how to approach the issue of wiring in the crossovers entirely. My first thought was to bypass the module entirely once I figured out which wires were for the input end of the crossover. A wiring diagram for the the module would be perfect. I have attached an image of the module below.

here's the problem. i have already figured out the wires for the output, i need to know which wires relate to the input for the crossover, these wires are shown in the image as the leftmost harness with the 4 wires. its a little hard to tell, but there is a gray, blue, white, and yellow, wire in it.

You can cut the harness, which I do not like to do, or get some of these jumper wires and connectors...

Break out the multimeter to trace each circuit. This is just off of the top of my head, but I think it would get the job done. And of course you do not have to purchase anything if you have the equivalent lying around.
