Prerunner VS Base 4WD - Interior Controls?

I’m going to look at buying my first Taco tomorrow. The owner originally included “Prerunner” in the listing but removed it after I pointed out in the description he said it was 4WD.
Are there any interior controls/switches or clues that would giveaway if it was a 4WD conversion or if it was 4WD from the factory? I’ll get under the truck and look or front axles/CVs.

thanks!

 

Call Toyota with the VIN. You may be able to google the VIN and determine which options came on it.

This worked for me.

Stock 4WD has the knob on the dash:


A 4WD conversion will likely have an actual shift knob for the transfer case:


The electronics/computer in the Tacoma transfer case make it an unlikely candidate for use in a PreRunner -> 4WD conversion.
