Hi everyone I'm in the process of swapping this 88 s4 13b turbo into my sand rail. Very excited!

But wiring diagrams aren't my friend and I'm new to the rx7 world.


I got a 88 s4 13b na emm harness i guess its called, and it doesn't the cas or coil pack plugs in it maybe more?
Wondering if I can send this to someone and have it added to the two orange plugs by the rubber grommet.
Going for a clean look since the harness will be hard to hide on a sand rail

Those are part of the front harness which runs all the way along the inside of the firewall and out the left side of the car. Adding those is no small task. I'd advise starting over with a new harness built from scratch. The FC harnesses are generally in very poor condition anyway.

should be able to take the two plugs off that harness that runs across the inside and just soldier on the new wires you need and not have 200wires. I would think.. I'm just not good with diagrams

Its more than two plugs. How are you powering the entire works? Main power runs through that front harness too. Switched power for the coils? Yep, need the relays and a method to switch them.

Two orange plugs plug into the emission harness thst runs through the fire wall.

Rest of that I don't know yet
