Trailing coil ignitor Wiring

Black- T1 ground (branded C1 on plastic plate)

Yellow - Tach (branded Tach)

Gray-Unknown (branded CPU1)

White(ish)-Unknown (branded C1)

Red- Unknown (branded ST)

Brown (x2)- Power (branded B+)

Green- T2 Ground (branded C2)

I am trying to wire up an M&W ignition to run my Wolf ECU , these are the directions I'm dealing with.

Anyway can anyone Identify the triggers for me? I'm not quite sure what to make of the CPU and ST wires?

Thanks

First off

im notsure if you have to use an ignitor with that ignition, so unless you have been outright told you do, id check that out

also fyi, the stock T2 trailing ignitor isnt a duel channel, its a fancy single channel where as the other signal wire tell's the ignitor which coil to fire.

I couldnt make it work and had to buy a FD ignitor (a 3 channel ) and wire it up from there, however i didnt use the mw box, i just ran the fd ignitor and fc coils.

Some information on the FD coil with wolf if you find out you do have to go that route

And to continue my post whoring..,

looking at the diagram you posted again, it sounds like you dont need an ignitor at all

in which case trig # would go to the corrispoinding wolf ignition output
coil neg # would go to the Neg side of the corrisponding coil

and well ground is ground

Thanks for the input, Wolf's website specifically says you will not be able to use the stock ignitor. I believe this is due to the fact that the stock ignitor is not in fact a duel channel , and the wolf ems is set up to run one out of the box.

However these are my discoveries

Red - "second trigger", I suppose that is what it was meant, upon tracing the wire back to the ecu and matching it with my Wolf Ems pin out it turned out to be the IGN 3 output.

White- C1 trigger, There are two C1 clips on the stock ignitor, however the black wire is the ground thus meaning the White wire must be the trigger.

Well thats it for anyone who cares lol. As a side note if anyone knows what the "CPU1" pin is for I would still like to know.

Thanks, hopefully this will be useful to some one lol.

Are you using a PnP wolf setup?

displacement is for losers

Yes sir i'm lazy, and no the PnP is not so Plug and Playish lol. To me PnP means umm Plug in and Go to town.... Not the case I should of just got a universal and wired it by myself. You wouldn't happen to know where I can find an s4 tII ecu pin out would you?

The fsm should have it, dont have a link handy

What version wolf do you have? v3? v4? v5?

displacement is for losers

v5 I couldn't find it in my fsm , maybe i'm blind I don't know, Hell I have the wiring book too and I still couldn't it lol. I can see all the color wires just nothing that tells me what the Pins are actually for

HAILERS2

None of my beeswax, but in the FSM, FUEL AND EMISSIONS chapter, there is a section called CONTROL UNIT. It lists the purpose of each pin on the stock ECU.

It shows pin 1M is for Trailing coil, and IGf-T which is feedback.

Pin 1U which is IGs-T which is the select signal.

Pin 1X which is IGT-T which is Timing signal.

Then go to the wiring for the coils which would be on the EGI EMISSIONS CONTROL and IGNITION SYSTEM page and find out what the colors are for those three wires above that run b/t the ECU and the Trail coil assy. Then it seems you'd look at the stock plug at the trail coil assy and match those colors with the wires on the trail coil assy itself. THOSE wires on the coil assy itself are a diff color than the wires in the plug, but you should be able to match them with the wire colors in the plug that attaches to the coil assy.

That makes some sense to me.

I don't know anything about PFC, only KFC and only then if trasfats ARE used. Screw the FP (food police).

Thanks man, I don't know why I didn't see the ecu pin out in the fsm. Hell that page may be missing but i'll check again when I get home
