The standard layout install of the Stereo harness that I use is attached below...

I normally run the output extension cable under the center console left side, under the driver seat and then door sills towards the trunk via the rear seat. The input extension cable is run the same way but on the right side. At the same time time I run the center and underseat woofers wires.

If there is a MOST connector at the Quadralock then it must be transferred to the new harness:

And if the woofers are to be independently powered then jumpers must be used at the OEM woofer connector so the front speakers can be reconnected to the input extension:

A custom MOST plug included by request with the harness in case of the OEM MOST plug not locking into the new harness (just transfer the fiber optic cables to the new plug). Jumpers are also included with the 6-CH woofer cable set.
