I've done this on a 95 GP actually. Its pretty easy to wire in but you have to rip into the donor car's wire harness pretty good to pluck out the required wires and chase them all the way back to their termination points and then do the same to your car to wire it in.
TBH if you don't have the option, (do check as DigitalOutsider said) its WAY easier to just do an aftermarket solution.

Look in the trunk next to where the antenna is. If it's prewired, there will be a purple wire hanging down. At least I'm pretty sure the late first gens retained the same RKE system.
If not, yeah, you could get the parts from a junkyard car and wire it in.

Um...if your speedometer now reads less than your actual speed...so does your odometer...you may be driving farther than indicated by the odometer, which would be reflected in lower calculated fuel mileage.
How far off would the indicated speed/distance be with tires that have a larger circumference? Find that, and you’ll probably discover the source of your lower fuel mileage
