The whole idea of doing this DIY was not to tap into any wires and instead use the city light pins and try to have a more 'OEM' like wiring.
Ahh. Either way, the pinout of 30 and 87 seems reversible.


You can also use a Resistor-Capacitor Low-Pass Filter to convert a PWM signal to a constant 12V. I don't believe there is a way to get a 100% duty-cycle from the LCM.

Edit:

Some google search says LCM might have some access to the PWM options per circuit via PA Soft.
