TB= Throttle Body The switch part is attached to said TB. Like on the picture below with a single switch. The switch is that little black plastic piece. You can see how it has a cam (the circular metal thing being messured) and it engages the switch at full open or close depending on the presure you have on the accelerator http://www.van-cafe.com/shop/images/throttle_body_part2.jpg Thanks to van-cafe for their picture. The newer version some 85's on have 2 switches. hope that illustrates the TB switch. Tony
