Trailing problem (cabels are cut)
I have just bought an 83 mod Rx-7 with a 88 TII engine.
The problem is that the "swappers" have just cut the harness to the trailing igniter.
I nead to identify the wires on the ignitor curcuit board with the text (take of the igniter lid c1, tac, cpu1, cI, st, +b, c2) these are not to be found in any wireing diagram in the FSM.
I dont think my trailing coil is working as it should.
Any one that can help me with who is who here (igt, igf ++)

How are you controlling the engine???
Stock ECU???
On a stock FC3S, the ignitors are controled by the "power harness" which is not integrated into the main engine harness.

I/We've no idea if your using the series four ECU or what. The wiring is clearly shown in the series four fsm from the PLUG of the coil to the ECU. But you mean they cut the plug off the coil assy? And now want to know how the wires ran to the coil plug????? I might be able to help if that's what you mean. I could scan a trail coil and the wires from it to the plug.

Sorry that i didn`t explain myself.
The ECU ia a stock fc4s mod. and the ignitors are controled by the x, u, m pins on plug #1 on the ECU. My problem is the "swappers" as i call them has cut the wires between the Ignitor plug and the ignitor so i dont have any referance to the FSM wire diagram. I need help to place the "pink, white, gray wires that you see on the picture, they is to be connected to x, u, m on the ECU, but where??????. I know the last wire (yellow) is the taco wire, and the two wires in the other plug are both 12v+.
Thank`s for replying.

I forgot about you. Here's a jpg.
The Grey wire goes to M on the ECU'S large plug as in 1M
The Yellow wire goes to a black, bullet check connector AND the tach in the dash.
The White wire goes to pin 1U on the ECU
The Red wire goes to 1X on the ECU.
There is another plug on the coil that has two wires. They both get 12vdc switched power from the Main Relay.
The two tan wires are 12vdc like I said just above.
