'04 Silverado Seat Heaters

Okay so my first install with the GM-U7 went well- only comment I have is that the seat heaters don't come on until I turn the key on- SO I suppose I should have wired in a third Ignition (I already have the pink for ignition and white for tranny)  I guess I'm somewhat disappointed that no wiring diagram chart says this is necessary, if it is true-- The only wire left is the brown- which I assume needs to be activated during remote start-- Also, the owner commented that he doesn't wish to have passenger side on- he sits his lunch box on that seat.. Nobody is ever 100% happy.  The GM-U7 does the seat heaters automatically when engine coolant temp is below 23 deg at start as I am told-- so should I hook up the brown wire- I have yet to check the service manual wiring schematic to be sure-- Thanks for the feedback- BrciddBrcidd - Engineer That Does Remote Starter Installs on the side.

The brown accesory wire MUST be hooked up, or transmission damage can happen

i just did an 03 Escalade that was with the GM-U7 and everything worked great..seat turns on in the low position... mirrors work...first memory setting... it was a fun install...all of those GM trucks are fun to do.... maybe the module is bad???????

No- the module is fine- I just did not know to hook up the brown accessory wire- the GM service Manual shows that the brown wire controls the accessories- The GM-U7 does not offer a +12 volt output for third Ignition (nor does the R/S module, so I can make one with a relay- I was trying to do a completely  relay "free" install- but looks like this is not the case.  I am just disappointed that Crimestopper GM-U7 did not have a note in the install instructions that some vehicles may need to energize ALL big ignition wires to assure that there is power to the seat heaters and mirrors.  I am just used to the pld GM installs where the brown wire did the wipers and radio only- and I always preferred to keep wipers off in case people leave the switch on and there is ice on the windshield the next day.  Thanks for the helpBrcidd - Engineer That Does Remote Starter Installs on the side.
