Somebody please move this if it is in the wrong place. I just have a question. I have a 1987 S10 Blazer Tahoe 2.8 V6 4X4. Does anybody know if my Blazer should be pre wired with the plug under the center console for a factory key less entry module? If so I would like to do plug and play to add a factory key less entry module It appears mine Blazer did not come with it?
