Got it! Easier than the W124!

Order the parts from Crutchfield, but order a DSL instead of a DSLV (I rewired the DSLV). Follow their instructions.

Here are some hints:

To find the correct wires to tap into, use JUST a lead from your mutimeter. Ground one end of it, and with the other probe the wires coming out of the pump (the red one is hot, so don't check it...). Mine were green/white and blue. One when briefly grounded will lock, the other will unlock when briefly grounded. They are the 2 wires you need! Unlike the W124 installation, you don't cut these, just tap into them (scotch connectors work great for this). Alarm works too!
