My 95 LS was pre-wired for the locker. Pull the filler cap in your console where the R/D Lock switch would be and see if there is a connector there. Also, the control module goes in the rear cargo DS side behind the panel. Ditto there on the connector. Lastly, there is a connector in the PS smuggler's cubby for the compressor. If yours is pre-wired, finding an SR rear would definitely be the way to go. Make sure you get the drive shaft from the donor.
