MSII board with MSD Billter Distributor and 6AL

[ian99rt]

Well I'm in the middle of board construction and a bit confused on the circuit I need to wire.

Using a SBC MSD Pro Billet Magnetic Pick up distributor ( only has green and purple wires coming out of it) and an MSD 6AL Ignition Box

The instructions are as follows:

With a MSD modules, the ignition module wires you need to know about are:

tach signal is a yellow wire (do not use this to feed to pin #24 on MegaSquirt® EFI Controller, it is for a tachometer only),
advance control signal is a white wire,
ground is a heavy black wire,
power is a heavy red wire,
switched 12 volts is a thin red wire,
the coil positive (+) wire is orange,
the coil negative (-) wire is thin black,
the unused VR signal wires are green and violet.

Hall sensor, optical sensor, points: feed the signal directly to MegaSquirt® on DB37 pin #24 by using the Hall sensor circuit described in step #50/52 of the assembly guide.
VR sensor: install and use the VR sensor circuit as described in steps #51/52 of the V3 assembly manual,

So..... how do I get an timing/ignition signal into my MSII if my VR green and violet wires are not used?????

Also should I install the pull up resistor in the IGBT High current driver circuit????

Note: If you are using the high current driver circuit to control an ignition module instead of a coil directly (and don't want to use the processor port directly - i.e., you have not jumpered JS10 to IGN), you likely need to to add a pull-up resistor. This allows the signal to go both high and low, rather than floating and low). Also, the IBGT will invert the signal from the processor, so your 'Spark Output' setting will need to be reversed.

You wire the green / violet wires from the distributor to the MS's VR input. The green / violet wires on the MSD box itself are not used.

You do not add a pull-up to the high current driver.

Matt you are the guiding light in my journey lol
