From the "live and learn" section of the Book of Life...it is MUCH easier to install the overdrive kickdown switch and associated wiring with the engine OUT of the car. Of course, I just did it the hard way. I had to remove the floor mat and pedal cover plates and then jockey the kickdown switch down between the firewall, shift arms, and engine and then, reaching thru the opening where the plates were, I maneuvered the switch into the hole in the firewall - not easy with big hands and a small opening. ***Important note*** The kickdown switch used in the HJ is not the same as used in the early Kaisers...I found that out the hard way as well. The switch used in the HJ has a shorter body so it clears the shift arms.
So, the switch and wiring is in place. The solenoid, governor and rail switches are all wired...now all I have to do is find an OD cable assembly. One question...there is a retainer bracket bolted to the rear of the transmission that the cable casing lays in to hold in it place when the handle is moved in/out. In it's proper position under the car, should it be up against the OD solenoid body? It's the only thing under the car that could act as the upper stop for the casing.
