Default 2jzgte, need vsv help!!!

Hi guys! I'm pretty new to this so I'm here to ask a newbie question lol sry...
IM swapping a 2jzgte into my sc300 and bought a wire harness from tweak'd performance. Every thing was going awesome until I noticed that the harness doesn't have the vsv connectors on it I want to ask you guys, is it necessary to have this switches? Or is there a way to bypass them or cancel them?? What's happening here, can yall help me out? I would greatly appreciate it!! Thx for your time

Most people just ditch the vsv's......They are not really necessary.....

This is the second case I've heard recently of a Tweak'd custom harness not including some connector. OP, what options did you specify in your order?

I want to thank you guys for your support, I got in contact with tweak'd and they told me I don't need them, they mentioned a mod called the TX mod, link below to be explained it case you guys want to try.

That is really surprising if you have twins and had a custom harness made that you wouldn't want the option to run it in sequential. I know what TTC is and not everyone likes it as the boost comes on more like a single turbo. Not adding them would make the harness easier to make though so I see why they assume most will TTC or go single but if you were wanting sequential I guess better ask for it.

I would recommend having the vsv for the sequential set up if you are running a stock auto, but if youre manual then youll be ok with the vsv deleted. I say it cause you wont hit full boost til 4k rpm in ttc.

^^ It surprises me as well. Unless you ordered their non-SC-specific "Universal 2JZGTE" harness or specifically ordered the Tweak'd harness with "single turbo" specified on the order sheet (which needs no VSVs) then something is not right with what you received.

I wouldnt make a big deal out of it people usually ditch the twins shortly after anyways.

^^ Sure, if he planned on that anyway or doesn't mind going single at this time. It would be a big deal to me since I am rebuilding stock twins and have to stay with stock twins for inspections. And I want them anyway. I'm still curious as to what the OP's order options were for his harness since they do have many variations for different setups.
