noob questions "injector risisters,knock box, ecm"

Got my car back from being torn down for along time 87 turboll trying to get it back together been read up on stuff and looking at why I got and noticed I have no plug or wire for the injector resister box. I did run it that way along time ago. So am I ok with out it or do I need to figure something out. Then noticed I have no knock control box or ecm control module do I need these or am I ok with out? Thanks for everyone's time and help in advance.

Car wont run without an ecm, injectors will fail or drivers will burn out of ecm with no resistor box unless a high resistance injector is used.

Sounds good thanks. Do you know where the plugs in? I though it was in the passenger side kick panel by the atmosphere sensor but I couldn't find a free connector down there

There is a metal protective plate (cover has 4 bolts) on the floor near the kick panel which covers the ECU.

The three plugs plug into the ECU. Not sure what you feel you need besides the ECU.

For the RX7 they're referred to as an ECU. You can find them in the classified section.

How about providing information which will tell us what you are talking about such as the number of wires in the plug to this yet to be determined device and the wire colors.

It have 13 pin on the module I don't know where it plugs in so I don't know what colors the wires are. If you go to the link that I posted the other day it's a pic of the module thanks again for your time

EGI main relay

That looks to be your EGI main relay that should be located near the firewall on the driver side the engine compartment I believe there are two plugs to the relay

It's not the main relay. That relay has two plugs, one w/2 wires and the other w/4 wires. You stated the item in question has but one plug for 13 wires.
