Hello everyone and thanks for taking the time to read. On my 89 Fox I have no brake lights. Now I have read a bunch of forms and Im coming up short here. All other lights work but no brake lights including the 3rd brake light. I have replaced the MFS, Headlight switch, hazard switch and brake light switch on the pedal (have confirmed power going in and out when the switch is activated). I have also checked the ground in the trunk to make sure it was good and it was. (Battery relocated to trunk and tested from battery to taillight harness ground and no voltage drop) fuses are all also fine. I'm assuming a broken wire but I'm not sure which color wire that runs to back to activate the lights. I have a book but it's old and hard to make out and unfortunately electrical is not my strong suit. Thanks for any help
