Thanks. I'll modify it to match your suggestion. I wonder why the manual specifiy these connections to the said terminals. Or I just may be interpereting them incorrectly. Otherwise, all other connections look fine?

DEI Viper manuals are written for their trained, authorized techs and are ( IMHO ) deliberately vague. Most wiring guides are suggesting one IGN and two ACC's. Did you verify all the ignition wires with a DMM?

Soldering is fun!

Everything kreg said is correct and I don't think you're listening that well especially with ref: to the red, RED / white and RED / black.

I've already said at least twice, that this vehicle has one starter, one ignition and two accessories. it doesn't matter which acc you nominate as the primary, just treat the other (wire it)as per second ignition.

Sorry guys. I can't really test anything right now since the car is in pieces. I'll charge the battery and test with a DMM ASAP. Thanks for all of your replies. Together, we'll get my car secure!

So here are my test results. They key cylinder actually has these outputs labeled!

Battery -white - no key, 12 volts

ACC - WHITE/ black - 12 volts when key turned to position 1, drops to 0v when starting

IG1 - BLACK / YELLOW - 12 volts when key turned to position 2, Drops to 8v when starting

IG2A - Yellow - 12 volts when key turned to position 2, drops to 0 when starting

Start - BLACK/ white - only 12 volts when starting

So I can see why you all say ACC and IG2A are the same. Maybe the "A" in IG2A is there to suggest it's an accessory also.

Also, on the key solenoid, they're bare solder pads. Looks like I can just solder a tinned 10 gauge wire to what I need instead of splicing the wires. Are there any objections in doing it this way?

Yes, no problem with soldering directly. And yes the yellow wire can be ignition 2 OR ACC 2 it makes no difference as long as you wire it up correctly.

So in all of this madness, I wired in a fuel kill switch with the idea of it being triggered by the orange ground when armed output on the H1 harness. But...I'm going to have a problem with remote start if I keep it this way won't I? I'd have to disarm the alarm to remote start but that's pretty dumb. Is there a way around this with keeping a fuel kill relay?

Replace your switch with this:

Use a relay thus:

85 = alarm GWA

86 and 87a feed to fuel pump from ignition

30 cut side to fuel pump

now do this with a second relay:

ground whilst armed to 87a

status output (GWR) from alarm to 85

constant live with a 3amp fuse to 86

other side of cut GWA wire to 85 on the original relay.

This will give you a fuel cut whenever the alarm is on except when you do a remote start.

Sorry, above post should have mentioned:

1N4004 diode in-line on both GWA and GWR wires just before the first relay, cathodes (bands) towards the alarm.
