I'm having trouble installing the ACC power controller in my 2017 Mazda MX-5 RF. I'm following the instructions that were provided, but the part that I'm having trouble with is releasing the C-18 and C-19 connectors from their shared plastic housing so that I can then connect the ACC power controller between the C-19 connector and the socket in the plastic housing. I see in the instructions that to access the C-19 retaining clip, C-18 must be removed first. But how exactly can C-18 be removed? Is there a tab or release button that needs to be depressed to release C-18 connector? If so, where is this tab or release button?
I've attached a photo of the housing that I took while lying on my back beneath the instrument cluster. Can someone help give a little more information on how I can remove the C-18 connector? Can the C-18 connector be removed just by gently tugging it from the socket (without pressing a tab or release button on the connector)?
Any help is appreciated -- thanks!
