My first post. Apologies for it being a request for help.

I'm working on a Honda Blackbird install. It's a carb engine.

The ECU has two identical wires side by side that are yellow with a blue trace. I know that one goes to the coils and the other goes to the TPS but I need to know which is which.

I think that the one to the TPS should be giving 5v with the ignition on but it isn't which hints at a fault with the ECU and isn't helping with tracing which wire goes where.

Does anybody have a pinout diagram please?

TIA.

Still needing help with This? I can check mine and report if you like.

Thanks but I sorted it out by trial and error. Luckily nothing blew!
