Wiring MSD 6A to replace the ICM (Ignition Control Module - Igniter)
Integra, EMS 30-1010, MSD 6A, Blaster SS Coil, MSD Cap
I just installed my MSD and wired it up in the following manner: (stock coil and igniter are gone)

After changing the Dwell Coil Factor setting to 20, I tried to crank it for the first time and got nothing. So then I disconnected the injectors plug and set the coil wire next to a bolt to see if a spark appeared. No spark when I cranked.
I then did a manual check of the install by giving the WHITE wire from the MSD a ground pulse and a massive spark crossed the gap from the MSD wire (from the Blaster SS Coil) to the bolt. So that showed me that the ignition was installed/wired correctly.
Now I've been trying to figure out why the ECU isnt giving me a ground pulse to set off the ECU. 93LSCivic said he wired his directly like this and it worked flawlessly. I checked continuity with pin B13 on the EMS (coil #1) and thats fine.
What needs to be done to get the EMS to ground B13?

you can by pass the ignitor? man this ignition crap is kinda confusing. i just installed a MSD digital 6 and am about to convert from internal coil to a HVC external.
what are the benefits of bypassing the ignitor?

The ICM is prone to failures, this way you use the ECU to trigger your MSD ignition directly.

i know this is an ooolllldddd topic but, anyone figure this out? i heard somewhere that u needed to install a 1 megaohm resistor inline on the trigger wire. is that what's needed?

It's actually a 1K (one thousand ohm) resistor, and a 1/4 watt resistor will do it. The tolerance is not very important. However, I have not tried it yet. I will soon though.
I had my stock ICM die, I'm trying to bypass it with an MSD 6a.
it's a TEK distributor, was a hitachi Icm. I don't have a white/blue wire at the icm, or the coil...... the trigger wire that goes to the MSD white should have pulsing signal, right? like pulsing 12v power? I'm not finding anything on a white/blue/green wire that's making a test light pulse.... I'm grounding out the test light ans searching for power, should I be clamping the testlight to 12v power and searching for a ground to make it light up?

the trigger wire shouldnt be 12v... you need a multimeter to test ideally... i think its a 0-5v but dont quote me
if he is running a system that allows you to change dwell settings then its stand alone and doesnt require the ignitor. if your running a honda ecu based EMS you need to retain the ignitor or you need an ignitor bypass circuit.
