No the seats were not a bolt up easy job!!! They were a complete PITB! I had to modify the floor to install them. The seat bases are integral to the seats so you have to use the GM bases or none of the motors would be there,,, each seat is a complete unit. I was only able to use one existing original Hold Down, the other three on each seat were fabbed by me. Here's a pic of the Drivers Seat.
Here's a pic of the Passenger Seat.
You can see the mounts I made, and here's a pic of the floor Modification I made to allow them to sit flat.
The seats are physically bolted to the top of the body mount plate on the Left and Right Rear drilled and tapped 1/2-13 as these are the seat belt anchors, on the Front Outside of both seats there is a 1/2" Tee Nut fiberglassed under the floor as well as on the Inside Rear of both seats. The front inside of both seats have a 3/8-16 Tee Nut from the underside. So there is three 1/2" Grade 8 bolts and one 3/8" G8 bolt holding these in place.
Please note: The floor was very close to the floor of a Steel Body. I had to make the mods shown to accommodate the seats which were a somewhat tight fit. The Drivers seat is right up against the inside of the door Jam, and there is about 1.5" on the right side from the Passenger Seat, don't ask me why? The Floor was then closed up and all fiberglassed over for reinforcement. The final touch was a Layer of Dynamat covering the whole Floor and Firewall. This all took weeks to months to complete.
I ran a hot wire to each seat from Switches on the Instrument Panel thinking I could figure out which pin in the plug energized the Seat Heaters. Short Version is none of them energize the seat heaters. The Computer under the drivers seat controls the Seat Heaters by way of 2 smaller door mounted Control Panels, and there is also alot of smaller mysterious things involved. Airbags, seat occupied, key on or off, size of your bum, how you're holding your mouth, and the list goes on.
There is alot of videos on Youtube about how to hook these up and none of them know what they are talking about! If it was that easy they would have been hooked up. The schematics that are available are completely useless.
In the big plug for the seats only two wires have to be hooked up for all the motors and Lumbar Support Pump to operate. The large Black Wire is the ground and the big Red Wire is the power. They are located diagonally from each other on opposite ends of the plug and I used 1/8" Female Spade Connectors to connect to the pins in the plug. The heater power wires were heat shrinked to terminate and are just floating.
Then the last thing was laying the carpet which was designed to fit a CJ 7/8 it was not even close and required a bunch of hacking and cussing to get to fit,,, OK,,,. I stuck it down in Strategic Places with 3M Double Stick Tape in case it ever has to come out..
It doesn't look too bad, but I have to say Carpet Installing is not my Strong Suit.
