VTCS Components

[Malevolous]

Hi all, just needed some clarification from those that have done the VTCS delete and not gotten any engine lights. The common idea is to keep the black box (Pic #1 & #2) plugged in and zip tied away. But recently I've read that the "Plunger" with the gray 2-way connector from the OEM IM needs to be connected (Pic #3). Can anyone confirm if this is actually the case?

I think the typical way is to keep everything in place and just cut the metal bar with the valves.

In my case, my car did not come with any of this installed. The IM was mangled so I replaced with a Corksport IM so I also don't have anywhere to plug these parts in to.

I did buy the part but it looks like there's just a dummy plug on top. The gray 2-way connector on the Mazda harness should be able to plug into this, but I don't see that actually doing anything since there's no electrical terminals here.

Small update, that part with the dummy plug is not the "plunger." The plunger is in the pics below. My car never had this or the black box. Hoping that these two will help keep P2006 away.

@Malevolous did this end up working for you? I have the plunger plugged in as well as the piece from the black box, but I am still getting a CEL

The first relay I was trying did not work, the relay turned out to be defective. When I told the person I bought it from, he sent another one that seems to be in working order, but still gives me P2010. When I took the relay off and plugged the OEM black box back in along with the plunger solenoid, still getting P2010. Not sure at all what could be causing it at this point. I also tried using a ziptie to keep the plunger closed. Doesn't make a difference.

I think I may have got it. I’ve driven multiple times, and no CEL yet.

I removed the center portion on the big black box, made sure all ports were covered just by connecting the hoses already there, plugged in the connector, extended the wiring, and there is a hole under the coolant reservoir where you can mount it hidden out of the way. As well as making sure the plunger was ziptied in the close position tucked up out of the way.

Maybe try it out to see if you get similar results?
