i am starting to build an rx7 i got a real cheap shell but its an N/a and im going to be dropping a tii in it. I know there are problems with the wiring for the drivers side N/a harness to the tii ECU. but i have the dashed pulled right now and i was wondering if i could switch out the driver and passenger harness put in the S5 Tii dash and harnesses into my S4 and have everything hook up and work properly till i get a standalone?

so i have S4 N/a and i want to put S5 t2 dash, harness, ecu and engine into it
