Re: Name that plug.. next to ECM
Thank you! I'm reading that it includes some ignition mentions... is it safe to disconnect and remove the plug? I'm running a 6al with billet dist.

Re: Name that plug.. next to ECM
Might want to check the cooling fan (D) and the ingition fuse (F). If your are running the stock cooling fan and ECM control, that may be doing something. Otherwise, since you are independent, old school carb and ignition, I'd say nothing on that connector is doing anything for the powertrain anymore. Just my opinion. Can't say for sure. Maybe just unplug it and see what happens.
