Question-What is it?

Just purchase a 2003 tacoma. there is an object on the roof attached to the rear brake light. Thought it could be a temp sensor but there is no display?? is it an extra antenna--sure has me puzzeled. Also, there are modules connected to the spark plug wires (passenger side only)- Where should I look for info-Nothing in the owners manual-FIGURES-is there ever.
2003 tacoma 6cyl sr5 4x4.

 

What does the object look like? Is it an antenna? It could be a cell phone amplifier. Pictures?

 

The modules on the spark plug wires are the coil-on-plug system, on that side the ignition coil for that plug is on the wire, instead of in one location elsewhere. Not sure about the object on your roof.

It could be a satellite radio antenna I know XM had one back in the day I don't know if they still do.

 

Here is a picture -if I can figure out how to load it
WTF i cannot figure out how to do it. Got the pic cannot get it to the post

 

THANKS GUYS will try again when i get a BRAIN

 

I'm pretty sure it's the optional XM antenna, my truck has one too and I also do not have XM. Wait... THEY'RE TRACKING US!!! No seriously.

 

Yes... because XM existed in 1991

 

We're talking about a 2003. Did you read the post?

 

Damnit sorry... I looked at the description in his info bar

 

If it's a small 'wart' object with a wire leading behind the third brake light's seal, it's probably an aftermarket XM or Sirius antenna.

Satellite radio was not a factory option through 2004.

 

Thanks Guys-guess i will need to get a sat. radio so I can use it. Have one at work --NO COMMERCIALS

 

My driveway is getting crowded-still have the 91 too. just cannot bring myself to part with it. When my son gets home from college-I'll post some pics

 

I've got something weird on my roof as well.... Does yours happen to look anything like this?

 

Oh one those. I keep mine under my toolbox.
