TCC Lock up

[orange57]

hey guys, i have an 85 Blazer with a crate 350. I just bought the thing, and i'm trying to get all the vacuum lines squared. I've been doing some searching and it says that the lock up on the torque converter is controlled by a vacuum switch. does anyone happen to have a pic of it? and where it is? and possibly where the vacuum line comes from that controlls it?

Thanks guys.

if youre like me and none of that stuff is still connected/there, you can get bowtieoverdrive.com lockup kit.

The first switch controls the lockup (only locks when throttle is not closed or near WOT). The second switch turns on when the TCC is locked, to control the EGR valve.
