Please DO NOT Post In The General Section

From this point on until otherwise briefed, posting in the general section of Performance Tech is prohibited. The only thing to remain here will be the stickies. We would just delete this section, but that would cause unintended results.


The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.


For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.


Everyone will get a couple of warnings from here on out, after that I just start deleting threads.

Again if you have any questions, PM me or one of the other mods.

    iab vacuum canister. black plastic box holds a vacuum, and the ECU tells the solenoid to open it up and it pops the secondary butterflies open via that silver plunger on the side of the itm.

    vacuum line w/ check valve from nipple on manifold to black box, from blackbox to solenoid, and from solenoid to plunger.

    two pin connector - black/yellow gets +12v (can be tapped at distributor, plenty of black/yellow there) and the other goes to the ECU.
