Maybe I am having a brain fart or something but I just got a turbo timer and rx7 harness.

Well, there is the timer, the box that the timer plugs into to along with the ebrake wire I believe then of course the rx7 specific harness.

I am needing to see if the harness should plug directly into the other grey box? or if that gray box plugs somewhere else instead of the harness.

Pic below is same kit just minus the harness since I got the FC specific harness.
