When I got my fd it already had the LT10S w/X4 but it was wired all messed up.

On the stock trailing coils, what wires go where? Signal on top? I cant remember. I have the molex plugs, but the wires were cut...

Ones a power wire, while the other acts as the swicthing/signal wire correct? Or is one a ground while the signal wire is the power?

 

No one knows which wire is which?

 

The factory wiring diagram may depict the pins on the connector. Once you get that you should be able to use common sense to equate that to the coils. IMO if you're using aftermarket amps you should upgrade the coils. I'm also wondering why you're using 4 amps when the factory leading signal is a shared to both rotors? I'm using 3 ignition amps with 4 msd coils, the leading is branched out two coils...

 

I have separate coils for the leading. TII ones...

 

Looking at the front of the coil pack. The left coil is your front trailing, the middle coil top to bottom is front leading and rear leading and then the right coil is your second trailing.

 

I know which one is which, the harness was cut before I bought it. I dont know which wire is power and which is signal on the molex connector itself.

i think it was thick grey for signal, black/red for power.
