I'm needing to file the sequencer to get my sequecial lights working correctly. The 1st two light up in sequence then the third one stays dark. I'm unsure exactly which piece is the sequencer. I know it's located in the trunk, but does anyone have a picture or anything so I know exactly which piece it is I need to take apart and work on? Much appreciation to any help given!

The sequencer is located in the wheel well on the driver side of the trunk -I will try to get a picture today (my cat is at another house being worked on) and post it here if someone else hasn't already.

File the sequencer?

Hey 67....what do you mean when you say "File the Sequencer"? I am not sure of the 67 Coug....but the 69/70 is a solid state unit (printed circuit board) and not sure what you would file on that... Just curious now what the 67's are like....

there is a board in at the side of the trunk down in the fender well, that has three motor type things attached to it - the middle one it the one that works the sequencer as far as I can tell. I wasn't able to make it to my car today, but definately will tomorrow evening and if no pics are posted by then, I will post what I have. You can also check out Vic's site at www.thuntek.net - he's the specialist.

dalerivers: apparently there are points that get corroaded (sp). If you file them down, the unit will work again correctly. That's what I've been told and that's my understanding.

Hey 67, The sequencer will have a white box and an electric motor underneath. You could just pry off the cover...it slides towards the front of the unit. If the contacts aren't the problem, operate the sequencer with the cover off and note its operation. I've seen one where two "points" did not operate ok....just removing the board on which the contacts are located and replacing it solved that. It's pretty simple actually!! And remember, it may not be the sequencer!:rolleyes:

PS. Dale...the 67-68 sequencers were not solid state... an electric motor driving a cam over three contacts (points).

Mine was working sporadically. I took the contact unit apart, dismantled the whole assy. took 400g emory cloth to the contacts and bent (bowed) them up just a touch everything works fine now. Mine were pretty corroded and i had to take a little "to much" off of em, is the reason i had to bend the arms a bit.
