No obviously pinched wires I did find the 5V from the R2LC loose when I was nosing around no idea if it was originally loose or if it came loose from me poking around.
The 5V from the R2LC is used to power the opto-isolators that feed the PWM speed commands from the R2LC to the DCDS If that connection was compromised, it could drive the DCDS a bit nuts as far as motor control. However, I don't think it would have anything to do with blinking marker lights.
What exactly is the purpose of the jumper from pin 5-6 on the 6pin power Molex. It appears I can bump that wire while on the bench in conventional and the motor stops. Think I might try replacing the Molex plug.
That's the eternal mystery! I've never seen explained what that was for, but I've never seen an Odyssey DCDS installation without it. Replacing that jumper might not be a bad idea. Getting the pins out of the Molex there usually requires the extraction tool or similar.
The killer is the extraction tool sells for $28, and it's certainly not worth that much! Before I had one of these, I used a thin piece of steel that I shaped similar to the tip of the tool.
Here's Rod Stuart's excellent page on the DCDS connections from his Motherboards document.
