I've got a project thread going over in the 1st Generation Forum but I thought I would copy the Electromotive TEC3 installation related parts to this forum in hopes that it might help those who would never look in that forum. Here goes. Installation of a purple box TEC3 into an '84 RX-7:

Removing the wiring harness (and engine):


Accessing the ECU:


Figuring out where to mount everything:


Everything mounted:


Machining a trigger wheel:






Gauges/radio mounted and wired:


Beginning to run wires (and new street-ported S5 13B installed):

 

Starting to crimp/solder pins to wires and install to plug:






More wiring pics:















This is very tedious work and is taking so long...

 

Is a great job the one that you are doing. I have an Electromotive too but is a Tec2.

 

Amazing work
