Engine bay harness to firewall connector question.

[Yoda's Master]

Anyone know how this connector comes apart?

[VStar650CL]

It doesn't. That's an oversized grommet, not a connector.

[Yoda's Master]

maybe connector isn't the right word, but it does come come off the firewall. I've done it on my other car before, but can't find the post that showed how without damaging it

[VStar650CL]

If that's a real old harness then maybe, but on everything since about the mid-90's those wires are loomed through a rubber matrix during assembly and then the grommet is taped in place. The wires are continuous, so there are no "pins" to break it with. You'd have to completely disassemble one side of the harness and then pull each wire back through the rubber matrix.

[Yoda's Master]

I don't want to pull the wires out. I just need t o remove it from the firewall to give myself more working space to feed a rca cable through.

In case some asks, I'm not going to poke a hole in it.

[VStar650CL]

Oh, gotcha. I thought you needed to disassemble it. There should be pawls on the plastic portion, you need to relieve them with a pick or screwdriver.

[Yoda's Master]

I know there's pawls to undo, but the question is how to get to it

[VStar650CL]

Not simple if it's tucked up in a bad place (which I'd imagine it is on most Infinitis). Getting at them from inside is best if it's accessible, and use a long hook tool to get at the pawl that's out of sight on top. If it can't be accessed from inside, you need to peel back the edge of the rubber boot and pry the plastic away from the firewall, then use some pressure on the part of the pawl tab you can see. On the few Nissans that use them, even I end up having to break them sometimes (and I'm damn careful). If you do need to break it, Gray Death will do a good job sealing it back up when the repair is done.

I hate this stupid firewall grommet. I would use the easier one in the brake booster cubby if I had infant hands to squeeze through the interferes.

I think I'll try one of those wireless video transmitter things and try to keep it from getting wet.

[VStar650CL]

Might be easier, yah. We all hate the damn things.
