i dont have lock up on my TC and i need to wire it up somehow. where are the endpoints and connector locations so i can find which wire i am looking for and if you have a picture of connectors that would be nice too. is it controlled by vacuum or wires? any other things i need to know. if a wire diagram would show it where can i find one? thanks very much. my aamco said they wouldnt do it because the wires have been modified. they are just unplugged emissions stuff. it under warranty anyways from the PO. thanks again and sorry for the lenghty post.
 
I used to have the same setup and i what i did was went to the local transmission shop and talked to them. What they said was there is a kit you can buy for about 100 bucks that comes with a silinoid and a fuze. All you have to do is supply a 12v wire and screw it in the case and it works great i ran it for about a year before i did a 465 205 swap.
 
well i dont have 100 smacks. i just want to plug it into the stock location. if i can avoid any cost right now that is my goal but that could be a last resort.
 
I don't know if 1985 was vacuum or not , but on my truck there is a little solenoid on the firewall with a wire and a vacuum hose , and of course there is an wire for unlock tied to the brake switch .
 
what color is the wire? is it on the pass side? the other side of that vacuum hose goes where? sorry for the questions...
 
The early truck setups were indeed vacuum. I don't recall all the specifics, but should be pretty darn easy to track down in a wrecking yard, or from someone parting one here.
 
hey actuall bowtie overdrives saves the day again, it has the basic principle of what 85 k5 4x4 had and is 70 bucks. i guess i will break down and buy it. thanks for you help
