I am in the process of replacing the factory HK stereo in my 2004 MCS from the ground up (HU, SPeakers and Amp) and based on the way I would like to do the install I am in dire need of a wiring diagram for the harness that runs from the door jam into the doors. (which color wire does what or even which pin-hole)

I am aware there are other ways to go, but I would like to do a complete rewire.

Any help would be greatly appreciated!!

 

For those that are interested, I have almost completed the install on my new system. Because I was unable to find details on the door harness, I decided to run all the wiring from the new amplifier to the existing wiring harness that was originally attached to the factory HK amp. While sacrificing the ability to upgrade to a heavier gauge wire, it certainly simplified the whole process.

I will post some photos of my install in the next few days.

 

I am about to install a new used amp (jl 300/4) - Craigslist deal... I have replaced head units and speakers and even installed an amp and sub in the boot, but to run new speaker wires to 4 channels seems like a huge job. A local installer quoted me $450.00 just for the labor! If I could recycle the existing speaker wires, it would not be such an intimidating job.

Are the new wires really necessary? Will the existing ones melt at high volume?

Appreciate any advice..

thanks
