neautral safety switch not working

I know on my car, we looped it with a jumper wire. A stiff wire. If you know where it is pull it out enough to work on it, use your ohm meter or look up a specific schematic, and jump from one to other. I only had 2 ports, it was so easy. like I said, look up specific diagram. Generally the sourcesnare endless on info. manuals a-z app is decent for certain ranges of vehicles. .........OR JUST REPLACE IT WITH A NEW JUMPER BOX. That, too, is simple. Good Luck.
