So Ive had it with blown ignitors and Im fortifying my ignition setup. This is what I got...

Car - 2000 Turbo GsR

Parts
- Mallory Hyfire Digital CD Ignition box (6852m)
- Crane cams PS92 High Performance Coil
- MSD cap and rotor
- Magnecor KV85 Plug wires

Im also trying to relocate the stock ignitor to inside the cabin for cooler temperatures.

Im trying to trace the wires from the ignitor to the chassis harness and for the life of me I cant locate them.



Wire #1 - Does this go from the ignitor to the ECU and then to the tach?

Wire #2 - Dont need

Wire #3 - Cant find it... Does this go to ECU?

Wire #4 - Research said this is B13 at ECU... Is this right?

Do these wire sustain the same color throughout... or do they change at the engine harness/chassis harness connection on the strut tower?

 

I know some of you must have done this before?

 

This is why I went with the MSD Pro Billet because the igniter and coil are external and can be mounted away from heat.

 

Im in too deep in my setup to switch to an MSD dizzy... I need the OEM sensors.

 

Wire #1 blue, my wiring daigram only shows it going to a junction and then to tach and tach test connector, but it must also go to the ECU/ECM, why not just extend the blue lead to reach the ICM.

Wire #2 pretty sure you will need it, it "fires" the coil, or in your case most likely signals your " Mallory Hyfire Digital CD Ignition box (6852m)".

Wire #3 black/yellow is the 12V+ ign. input, [power for the ICM] should be hot in run and start.

Wire #4 my wiring diagram only shows ICM on the ECU/ECM, but it appears it is the only yellow/green at the ECU/ECM. 94

 

First off, thanks so much for taking the time to go through your diagrams and write such a detailed response.

Oh, I should have explained that when I said I didnt need wire #2, its because I dont need to trace it because Ill be running a new wire from the ignitor to the mallory box.

I have enough information to proceed with this install... Thanks again, it is much appreciated

 

please post back with your install and pics... I'd like to see how it all works out.

 

For sure... I havent had much time to work on it, but the harness is almost done so Ill snap a few before I install everything.

 

So everything is ready to be installed and here are a few pics

Ignitor next to an ignitor bypass circuit I also made


Im using an OBD1 Dizzy so this is the adapter harness and the 3 wires that were extended into the cabin


Mallory with ground and Coil wires


The entire harness

 

So I installed everything and it didnt start with the ignitor... I hooked up the ignitor bypass box and it started right up. What could I be missing here? Im still troubleshooting but any ideas?

 

Did you ground the ignitor?

 

Old.... But how is this working?
