i'm trying to find the wiring diagrams for the surveillance light switch... there was something else but it eludes me at the moment.... i have only been able to find snippets of information regarding an unused wire on bcm feed that kills speedo lights, if i recall correctly, but nothing of the rest of the interior, or head/tail lamps.

Thanks for any help you can provide.

Anyone here know anything about diagnosing electrical problems? I have a 1990 toronado trofeo that i am going to push off a cliff soon. There are a plethora of sensors, relays and other sh*t and I don't have the money to have a shop do the work for me so i am trying to fix a couple of the main problems myself. Any help would be greatly appreciated!!!

The Impala 9C1 marked and 9C3 unmarked police package comes with a supplemental manual in the glove compartment that covers the police package options including wiring diagrams. I would suggest looking there first. I don't have one in front of me now, but I have a manual at my shop.

The Surveillance Mode Switch (SURV) is located in the instrument panel to the left of the steering column. When the SURV button is pressed in, all automatic exterior and interior lighting functions are disabled. Pressing the button again activates these lighting functions. All lighting functions can be activated manually if necessary.

In daylight, the daytime running lamps (DRL) are off and the transaxel shift indicator (PRNDL) and clock/radio are at minimum intensity. At nighttime the automatic lamp control (ALC) is disabled: exterior lamps, interior instrument displays and dome lamp are off and the PRNDL, clock/radio displays are at minimum intensity.

Last month my service manager went to a meeting at GM in Detroit to discuss the changes and new design of the 2006 police package Impala. So we will have one more year of the current style before they completely change everything and we have to learn another new one. We don't do too many Impala's anyway. Only a few hundred a year. Hopefully equipment manufacturer's will keep up to date with appropriate mounting brackets and electrical connections.

" that covers the police package options including wiring diagrams."

Thats exactly what i'm looking for, for the surveillance mode switch. I have no pre-existing wiring i am sure, but the diagram should show me the necessary connections etc.

thanks

Sorry, I checked the mannual yesterday. It does not cover wiring for the surveillance mode switch. It covers the functionality but not wiring. There are several wiring diagrams in the manual which cover adding common options. It details the harness coming out from under the dash, including relay diagram, horn ring loop circuit, ignition, accessory triggers. The manual also covers detailed pin assignments for Headlight flasher metripack plug under hood, wiring diagram for adding taillight flasher to plug and socket in truck, factory spotlights, deck lights etc.

I thought the info you were looking for would be in that supplement, but I guess that I was wrong. Not sure where you need to look for this info.

john9912- thanks for looking for me, this is proving to be a very difficult bit of information to get hold of. The troubleshooting for the switch is simply applying ground, thats all the button sends to turn on/off, so i'm figuring it is most likely straight to BCM.... the only information i have found on that however is that there is a trigger on earlier bcm to kill DRL only (same application of ground to trigger).

I think i'm going to have to find one i can poke through to figure out whats going on in there.

Thanks again for checking.

Can you verify BCM connector C2, pinout B7 is interior lamp kill and ifso, if signal is ground or ground pulse (or neither?) ?

thanks
