on the golden fluid pipes the wire is blocked form conecting but above on the structure pipe it still conects

Wires are supposed to jump from pipe to pipe, this is the expected behavior. As a matter of fact, the unexpected one / or inconsistent one / is the one of the pipe plug blocking wires.

I think wires need their own plug, like a ring that goes around the pipe (so it can be placed with normal plugs too), and blocks the wires.

I think the intended behaviour is, on normal pipes wires cannot cross gaps, but with structure pipes they can. With the gold pipes the plug is creating such a gap, and the wire cannot cross it, but on the structure pipe the gap is ignored.

ok, i cause it blocked on the fluid and not on the structure i thought that was the error, i'll update the title

@Forecaster - yup, that might very well be the case. Anyway, closing this issue.
