VNT W\G solenoid same as TI??

[kpic]

Converted VNT to TII, I want to use the stock VNT w/g solenoid #1 (the one next to purge) as the control for my turbo. I need to hook it up like an 89' up TI (custom cal).

The stock solenoid has "2439" stamped on the back but I cannot find a part number for it. Can anyone confirm that the 89' up w/g solenoid for a TI is the same as the one I have?

I think there are a few differences with the w\g solenoids through the years.

think VNT solenoids are specific to VNT only

#1 (shock tower) & #2 (1st solenoid next to shock tower) I know are. But as I have a custom CAL I can unplug each of those without a CEL except for #3 , tells me that is the one that controls boost signal, I just thought someone could give me a confirmation part number.
