I dont remember what we did with the 5th gear switch wires. It's never affected the car.

The engine has two mounts - one on either side - so I suspect by disconnecting the mid pipe and the tranny bracket (we had a custom one made since this is a Tii in a vert) the tranny will angle down enough so we can get at it.

I was thinking about dropping the tranny mount too, but I don't think that would result in enough space either. There's not much clearance between the firewall & the engine block for it to pivot back, so the block will probably hit firewall before there's enough clearance at the tranny to get to the switch.

From what I can gather from the FSM, the 5th gear switch is used in part of the ECU's decision logic for operating the fuel/air maps in closed loop mode. If you drive your FC like most of us do, you probably won't notice any difference. The majority of the time, it will run open loop; closed loop running only happens under "granny driving" conditions - low load MAPs and a narrow range of RPMs, below where the secondary FIs kick in.
