yes they work right, what do you want me to tell you. listen i have them and if your looking to buy one with a tach i am selling them. I'm not mister no it all, but i put it on my tour and i have picture and it runs fine. Idles at 750 rpm and works according to speed. if your interested just buy one and see it for yourself. All I know is that they cost more than $90 to buy brand new from ford.
