Help?BOOST BY-PASS KIT INSTALL/ Which VAC Lines?
Hi guys! Search not working for reference. Received my kit and need to know which vaccum lines to attach T to. Don's ZR1 Killer was nice enough to supply photo and I can't find it on search. THANKS!

Trying this from memoery:
1. The pink vacum line going into the boost by pass relay...... pull it out.
2. Put the srew that came with your kit it the rubber boot you pulled the pink line out of on the realay.
3. Find the boost guage vacum line coing out of the top of the firewall. It has a white connetor splicing the line together.
4. Take the white connector out and put your new "T" connector in.
5. Take the piece of hose that came with your kit and out it on the "T".
6. Take the pink line you had disconnected from the boost bypass relay and inset it into the hose you added to the "T".
Hope my memory served me correctly.

Another tip that makes getting a pair of human hands in there to work on this, is to remove that bolt(in upper left hand corner of photo) that supports the brake booster vacuum line . Then pull out the line from the booster and push it aside. Now you just made the job a lot easier. BTW, don't forget to re-attach it!

This gets the same this acomplished with stuff from the autoparts store
Remove the pink line from the top of the boost control diaphram valve, (not the selenoid valve) and plug it with a 1/4" bolt cut to about 3/4 inch long but that still has about 1/4" of smooth shank so you don't get an air leak, or use a 1/4" hose mender and a 1/4" cap.
Next, get 3/16" Tee to put it into the boost hose that goes into the firewall and up to the boost gauge(there is a white 3/16" hose mender in this location stock). Get 9" of 3/16 fuel rubber fuel line to go from this Tee to the top of the boost control valve.
The result is the computer will no longer have the ability to dump boost at the shift (torque reduction) or as part of the over-rev protection. THe computer will never know and will not throw a soft or hard code. The boost bypass will still be active at idle thru near zero vacume, and closed shut in all boost conditions.

Your picture doesn't look right... from what I've read... the pink vacume line from the boost by pass relay is tee'd back into the boost line to the boost gage.
At least that's what I've got in writting from others.
Is this another method?
It also appears that the pick vacume line is still attached to the boost bypass relay.
Hmmmm.... yet another choice?
