I am buttoning up my 2005 LQ4 swap into my jeep scrambler and was wondering what source of vacuum on the LQ4 do you guys use to hook up the vacuum modulator on the th400. I searched on here but couldn't find it.

Also thinking of modifying my pedal for the kickdown switch but was reading some use and some don't. Is there any benefit to keeping this switch?

Thanks in advance for any help!

Any manifold vacuum source will be fine. The kickdown switch is entirely up to you. If its going to be a driver, I would put it on so you won't have to manually down shift it.

 

if you are using the stock intake, there is a little tab on the RR intake manifold you can break off for a good vacuum source.
