Alternate ECU ground location

Looking for some advice on a potential alternate location for the ECU ground that runs to the rotor housing. As some of you know, the IRP IGN-1A Plug & Play Ignition System has two grounds that run to both rotors. With this, where would you suggest running the ECU ground now that the previous location is being utilized? I've been able to find great write-ups on correct ground points throughout the forums, along with Aaron Cake's guide, but nothing that specifically addresses this. Car is a RHD 1992 RX7 FD. As always, thanks in advance. Look forward to the knowledge.

You can stack grounds. The m6 holes on the top of the transmission work as well if you don't want to do that. There should be more than enough length to reach

Depending on where you mount the coils and terminals in the kit, usually found the 8mm bosses on top of the rotor housing convenient,
