How do you count the relays, it looks like a T laying down with top of the T to the left but the XJ Handbook 4-22 just says
R1
R1 R1 R1 R1 R1
R1

So how do you know which is R5? Besides like I say the driver rear stop lamp works? Suggestions?

If I count straight down on the top of the T R3 is missing and come back to the middle of the T R6 is missing? In other words

R1(R1)
R1(R2) R1(R4) R1(R5) R1(R6) R1(R7)
R1(R3)

Is this how they are counted?

 

Could somebody give some advice on this because I need to drive this car at night and hate to get a ticket for a brake light out? Or after troubleshooting what I could above do I need to take it to a shop? (maybe something wrong with the wiring)

 

The brake light is controlled by a slm module located in the trunk. They are know for having an issues with chips burning out (specifically the right brake light chip). Also, do not connect a wire from the left brake light. This will burn out the chip for the left in a month or so.

You should do a search on the forum for threads relating to this. There has been quite a bit of discussion on the process for repair.
