My secondaries are not opening at 6k like they should be if everything was wired correctly. I was told that when the secondaries open the rod on this diaphram will go down.
Just went out and took a look and with the motor off the rod is DOWN:

When I rotate the clip around the rod moves up toward the hood / shortening the rod:

When the secondaries kick in at 6k should the rod be down like in the top pic or up as in the second pic?

Thanks!

i have the same problem. i have 92 si with 94 jdm gsr b18c, i reeved it up to 6k and the little stick did not go down. all i remenber doing when i did my swap was move tha A20 to A17, i dont remenber moving a black wire. and give it 12volts or something like that . what else do i need to do to besides moving the a20 to a17. thanx
O.K. the diaphram gets vaccum at idle, the diaphram raises the rod. The secondaries are closed for high torque at low rpms. Around 6k the diaphram loses vaccum from your wired selinoid, therefore droppin the rod to open the secondaries for maximum horsepower at high rpms. I've personally taken one apart an the secondaries were open. When i pressed the rod up in the diaphram, they closed.
