RX7 FC 12V Switched Ignition Source

RX7powered · 01-13-2016, 11:57 PM

Hello. Before I begin, do know that this swap is my first time to wire and I've learned everything by searching, but I'm stumped about something and I didn't know where else to turn besides the main forum that knows so much about these cars.

For my electric fans and fuel pump, I've used the AAS connector and your typical relay setup to power these items.

The Problem: I'm trying to get 12v switched ignition power to three 10-12 gauge wires for my 1JZ harness; they power TPS, injectors, and igniter. I was thinking main relay but I wasn't sure and didn't want to hack anything up. If someone has an intelligent suggestion on how to power the essentials in my harness, please advise me; and I thank you for your knowledge.

Disclaimer: I have been a big fan of the rotary engine for a long time and still own my rotary engine, but I wanted to do something different and be able to show that I have learned things and applied those things to a project.

You're talking about running those wires through a relay?

Do you still have the "power" harness in the engine bay?

What I would like to do is use a distribution block and power it with 12v switched ignition -- he only wires that I know of that provide this are the AAS connector wire and the black/white wire coming from the green connector on the front harness. I didn't think those small wires would be enough to reliably power the three wires that I need to power with 12v switched ignition. That being said, I do not know much about wiring, just what I have learned by reading a few guides on how to set things up here and there.

To give you an idea of my setup, I have everything but the engine harness on the car. Right now, I have a battery relocation using the guide listed on (your) FC3Spro.com.

Thanks for your time in this issue, I am very grateful.

Just pulled my main relay, decided that I'll probably just chop the connector off the side that powers the coils for the rx7 and and mate the 1jz injector and igniter wires to it.

But, the wires on my relay aren't true to the FSM...
The fsm shows for Non-Turbo 1989-1991 Models (this is a 1990)
Two Prong Connector: Black and Black/white. Mine are black/yellow, and white/black.
Four Prong Connector: Black/white, and black/yellow, White/blue, and White/red. Mine are Blue, another Blue, Black, and Black/yellow (possibly white, age).
Help? I'm very confused.
