avistart 4100, ’06 vibe, accessory wire?

Read this schematic again (if you didn't the first time) page two (2)

...notice there is a white wire (AM1) and a black wire (heavy gauage AM2) ---> the white wire powers blue/red and BLACK / YELLOW and the black wire powers BLACK/ white and red.

So the two circuits are powered separately (white = accessory and igntion_1) (black = igntion_2 and starter)

At this point, I would run a separate line from the battery  -- don't worry about running it through the firewall yet --- and let this power both your red module power wires (with the 30A fuses).  Let me know if this solves your problem. 

I wouldn't mess w/ the BLACK / YELLOW ignition wire the way you were suggesting.

Also --> check AM1 and AM2 fuses under the hood (25A and 15A respectively) 

Also --> check BOTH fuses in the red module wires (30A fuses) .. make sure these both are ok and one isn't blown.

According the the schematic

< color=#810081>http://www.illformedpragma.com/matrix/reference/repair_manuals/2003/Wiring%20Manual/systemci/012ps.pdf

the BLACK / YELLOW is responsible for heater, defrost, a/c ...

the blue/red does the radio and cigarette lighter adapter (radio isn't listed on the above schematic, it's pages later in the service manual)

All the BLACK / YELLOW wire does is provide the 12volts+ to the coil of a relay (see schematic) that allows power to run through a circuit that powers heater,defrost, a/c, ECU, washer, wiper front and back.  I imagine that b/c when you apply 12volts to this relay (BLACK / YELLOW) and provide the ECU more power... it shuts the engine off for whatever reason.  Be careful with testing this BLACK / YELLOW wire b/c you could fry your ECU -- $$$$;  Either your r/s brain is defective or something is fishy with your install and you're missing something.

One more thing you can try:

Relay power to that BLACK / YELLOW wire (and disconnect the pink/white [ r/s module] from the BLACK / YELLOW wire)

85: connect to Vibe BLACK/ white wire

86: chassis ground

30: 12 volts fused +

87a: BLACK / YELLOW wire on Vibe

This will insure that 12 volts is sent exactly at the same time to IGN1 as to IGN2 wire on the Vibe.
