The tach worked with the last three swaps in my 98 integra. swaps were 98ls 97gsr 94lsand now a b16a. all swaps had the same harness from the motor excpt the b16, it has a 2000 usdm itr harness. the tach just sits omn zero but every thing else works. has New plugs wires and a good distributer. I am just tired of fooling with it and wasting money if anyone can help please do. Thanks Rob

same thign happen on my friends integra now that I think of it. 94ls with 2000swap and 2000 harness.
