S2000 k24swap fuel rail ground

[Ap1s2k24]

hello,

I had asked around on facebook and heard from professional tuners, but would also like a direct answer from you guys at Hondata. Iv swapped a k24/k20 with the s2k intake manifold and fuel rail into my s2k and am using kpro. My question is, do I have to put the ground into the valve cover, or can I put it on the block? I have a ground from the motor to the frame rail, as well as one the the engine bay wall. I don't want to damage my ecu, but I don't like the look of the wire on the valve cover. Thank you.

It needs to be grounded somewhere on the cylinder head.
