How To - disable auto headlights Tahoe

There is an easy way to disable the auto headlights on Any 01-02(Includes Silverado, Suburban, Tahoe, Sierra, Yukon, Yukon XL, Denali, Denali XL Truck) so it won’t blow out your hid bulbs and ballasts.

Cause: I have gone through a set of hid already that is why I’m doing this mod!
Hope it helps, enjoy your Mod guys and be safe!

First of all you will need one 1.5kOhm resistor From Radio Shack.


Disconnect your Vehicle battery both – and + terminals.

Remove lower dash cover panel from driver foot.

Locate the BCM” Body Control Module”

There are three connectors plug into the BCM, disconnect the connector all the way to the right which is “purple”

Locate slot 3 and 5 from left to right: white, and gray
Be careful there are 2 grays

Cut them separate from the harness and tap them with a resistor

Tape up the other end of the harness so it won’t short out.

Plug it back in reinstall everything removed.

To test it start the hoe up with the parking brake on release the handle, if the lights doesn’t come on (((By Pass))) is now completed!

If you need help or question please pm me !

perhaps but it would be better for you to just turn them on manually rather than having them flash when you crank over the engine. Any chance of this working on an 04?.

04 or newer I believe it has an auto switch to turn it manually. It would still has DRL " Day time Running lights "

where in northern virginia do you live?

Around Springfield Mall .

i did that mod like 2 yrs. ago and no problems to this date with manual headlights
.

nice i like it

Thank you for this write up with pics on the 01-02!

One real quick question .. I have a 2002 Tahoe in which I will soon be doing this mod to for my new set of HID's from DDM .. question I have, does doing this mod effect the DRL's at all ?
