no kickdown on my 91' k3500 burban 400 turbo

I have had this Burban for some time now and just dealt with not having a kickdown on the 400 turbo.Need a little help on how to install a kickdown for a 400 turbo.

thanks

You'll need to a lockdown solenoid. It plugs into the transmission, has a 12V power wire, and then you'll just need to clasp it to the TBI. It'd probably be best to find the hardware in an 87-90 square body that has/had a TH400. Was this a half ton that had a 4L60 and someone converted it to one ton and put a TH400, or was it a three quarter ton with a 4L80E?
