So no, ecu is irrelevant for those items to function.
I can't help you with the speedo/tach wiring, however. Although, for the speedo, you can buy a little module to intercept the signal and correct it. essentially it's a little gain knob, so you can turn it up or down to increase/decrease the speed signal so that it's accurate on the dash.

its a wiring specialties harness they have everything labeled on there website luckily. thank you for explaining it is on a separate harness, thats something I was very confused on.
and I was able to find a module that is able to intercept both speed and tachometer so I should be set
