Default MS3 Basic '99 - looking for HOT (+12)

I have a Reverant MS3 Basic. Is there a +12V (not switched) available on the DB37? I want to run it to my Innovate G5 gauge.

No, you need to get this from pin 1A on the OEM harness. I don't remember what color it is on a 99, on a 01+ its a blue/red wire.

Pin 1A is BLU/RED according to the wiring diagram (mine is a 2000 so I expect it's the same).

Also its on the 22 pin connector to help you track it down.

Thanks. Rev, do you never sleep? A couple of other questions, while the DB37 loom is still out of the car:
1) What leads do I need to add to the DB37 to run sequential COP's? In other words, what pins go out to the other (2) ignition coils? These would be the Brown and the Brown & Green according to your instructions, but my loom does not have them. Would I also have to solder drivers to the PWB? If so, where?
2) Do you have a schematic or a full pin-out of the DB37?
3) What would I need, internally or externally, to utilize the digital output of the LC-2 as an input to the MS3? Or is there really any benefit over using the Analog?

My S/N is 12616

You need the external wideband-to-CAN module, which should hopefully be available starting from next week.

Code:
Pin	Function
1	Fused 12V
2	Ground
3	Sensor Ground
4	Wideband In
5	External MAP
6	Ign C
7	Ign D
8	CANH
9	CANL
10	RPM out
11	EXT_MAP Input
12	SPARE_ADC Input
13	PT2 Input
14	Tableswitch Input
16	EGO2 Input
19	Nitrous2 Output (3A Max)
20	EBC Output (PP3)
21	Ground
23	Nitrous In
36	VVT Output (5A Max)
