This is my newest TPS product. It simply plugs in and allows you access to the different voltages produced by your ECU or signal voltage coming from the TPS. There is a great review that can be found on the Snowest forum if you search "Where to buy a TPS tester."You will need your own voltage meter. THIS IS NOT A STAND ALONE PRODUCT! If you are using this on a sled, you will also need a power-up cable to energize your ECU or start the engine. On Rangers and Razrs you can simply turn the key on and set your tps voltages. I'm still getting to know all the products this fits on. Please send me your questions BEFORE you buy the product. If you purchase it, I'm shipping it! eBay doesn't allow for any lag in time in shipping. It impacts my performance rating when a buyer "buys" the product and then asks all the questions that should happen pre-sale and I end up not shipping it on time because of the questions! READ my feedback. I try VERY hard to be a no BS seller. I ship as soon as possible. If you bought the wrong one because you didn't ask the right questions, I'm sorry! If you buy it and I guided you wrong, I'll make it right. PERIOD!
