Bought this product for my 1988 Ford Ranger; the original TFI module no longer works. I have purchased Pertronix products and have had positive results. However, this time the Pertroix module was found to be inoperable upon reception. I returned the purchased unit to Pertronix and received another unit under warranty. I was still having problems with the new device, I couldn't get it to work properly. At this point it was necessary to purchase an additional unit from NAPA to get the machine running. In Pertronix's defense, I didn't bother to guarantee the second unit. I accepted the loss and moved on. Time was a factor and I didn't want to bother with the product warranty return and refund process through the postal system. As I mentioned earlier, I've had good luck with this company and their products, unfortunately not this time. I gave the product two stars due to Pertronix's reasonable response time regarding a defective product warranty. To rate a product in terms of functionality, there would be no stars.
