how to disconnect turn lights switch
 

Hi

I am not sure if this forum is proper for this question. If not please forgive me.

I have 2000 year Blazer with airbag. I need to do some modifications with my electrical system - change brake lights and tail turn lights connections. Need I remove steering column covers and steering wheel to work with cables? Any idea? Maybe I can remove only instrument cluster to get cables but how to identify what is brake light switch cable and what is from turn signal flasher cable?

Marcin,

If you just changing the rear tail light housing to replace factory with aftermarket you do not have to change anything in the dash. There are harnesses in the back of the Blazer that are connected/disconnected with plastic connectors. Are you going with Euro style tail light housings. If that is the case then you should not need to change anything unless you are having contact issues with the bulbs. The bulb housings should just rotate out of the factory housing and into the aftermarket housing without a lot of hassles. All you have to do is to remove the trim in the back of the cargo area to get at the nuts holding the tail lights to the body...

It is not so easy. Now I have every taillight consisted of three bulbs: two of them are taillight/turn/stop and one is white lighting in time of backing up the car. Now I have to install European lights with separate taillight, amber turn light, separate stop light, tail fog lamp and white one - see the picture.

So I have add some wires and change existing.

WOW... That's going to be quite a challenge... In the US spec blazers, the brake lights get routed through the turn signal and hazard switch before anything goes back to the lights. Basically you are going to have to remove the brake feed to the turn signal switch and run new wires to the lights...

Let me see what I can find for wiring schematics to see if any of them make mention of this type of configuration.

I am afraid of two things:

1) removing steering wheel. I found old thread with procedure of changing turn light switch with no word about steering wheel removal but point 5 "Remove the steering column upper and lower trim covers. Refer to Steering Column Trim Cover Replacement - On Vehicle." seems to be dangerous to me becouse in Haynes they told to remove steering column covers I had to remove steering wheel :(

All your procedure here: https://blazerforum.com/m_15006/tm.htm

2) removing panels in car to put new wire. What is the best way to put it?

I have two days to do it. And I hope airbag deactivation and activation procedure will no cause any problem to me.

Another (last one) question is how to remove panels to put new cables and not to destroy panels?

Sorry for not understanding your situation having to convert it from U.S. to Euro tails...

I am wanting to do that for here in the U.S. for my truck how much you pay for those....
