Re: Spike Relay Input

Does anyone know the pinout to the Spike Relay module where the PWM cable plugs in? I'm guessing that black is ground, Red is Power (+5V), and Yellow/White is the input.
The input to the Spikes is two opto isolators with resistors in series. They each drive a transistor which switches the coil currents. The input to a Spike, and the Relay outputs from the RC, are ground (black sounds good for this) and switched positive voltage on the other two wires, one controlling each of the two individual armatures of the relay.

info:
The Red Spikes' output terminals both rest connected to ground, and when either one of the two coils is energised, the armature corresponding to the energized coil, is brought to +12V., and current flows in the output load either to the grounded other armature terminal or, if connected as permitted last year, to ground.
