Wiring plug identification help needed

[cdnwillyg]

I have a new project that I bought 2003 TJ Sport that was totally disassembled and in the process of putting it back together I have run into an issue. First off do they use the same wiring harness for all option TJ's? Mine does not have cruise or AC but in the dash wiring harness i have some plugs that don't have any where to put them. One is under the drivers side dash, one is on the steering column, one down by the air bag module and the last up on the passenger side dash defrost. Any help in identifying them would be greatly appriciated.

The one on top of dash is for the rear view mirror with compas, outside temperature and map lights. There is another wire harness that runs up the passengers side A pilar that is needed to connect the one on the dash to the mirror itself.

Thanks Tom, I dont have that so extra. Any ideas on the others?

Can't make out much on the first picture. A clearer picture might help.

Second pic looks similar to a connector for the wiper controls found on the Multi Function Switch on the steering column. Not sure though.

Not sure on the third pic.

The FSM has a diagram of all the connectors (go to Wiring and then Pin Outs). You should be able to identify those mystery connectors using the shape and the wire colors. Here's a link to the FSM's....

Just an update on what I have found, the first pic connector is for the brake lamp switch, the second for the multi function switch C2, the third is for the G switch, not sure what to do with that? It says near T/O for controller Anti-lock brakes. And the last one for compass/temp mirrror, although different color connector wire colors check out. Gret manual for checking the wiring out once you get the hang of how to use it...Thanks Tom! Now on to the interlock between auto trans and ignition switch lock out, something not right there???

Glad you figured out what they were.

What’s happening with the interlock?

The ignition to trans park is working, I think. When in park the yellow plunger is down in the ignition and up when trans is moved from park but not doing anything? Now I'm not to sure what that is to stop?? Do i need power on for this to work as it should? I moved my trans shifter after i hooked up the cable and forced it out of park not so sure that was too smart, the cable wont retract now. I read after that the brake needs to be activated, power on then moving the trans shifter...not sure all new to me!!!

Sorry for the delay.

I'm not sure I can really knowledgeably answer that, but I did find this info in the '03 service manual. https://wranglertjforum.com/attachments/2003-tj-service-manual-pdf.14041/ Page 1276 of the manual.

Thanks Tom, I did figure out the problem. The last person didn't have the little kog in place to inhibit the shifter and had removed the spring to eliminate the steering wheel lock, all good now I think, I'll run it this way until I find an issue. Thanjks again.
