The extra relay restores a ground path and normal function, but is only necessary for the '67 RS cars.
I'm going back with electric on mine Brian. So it looks like another couple will have to be installed??

Re: 67 RS headight harness upgrade - adding relays or relay harness

Hm. If you've removed a stock '67 RS harness, relay board, motors, and limit switches to install in your '68 then perhaps. If you're using any kind of aftermarket electric conversion kit it's less likely as they probably wouldn't have engineered it this way. Also, the install of the light relays is the same as any car, it's just the addition of a fourth relay to the original three on the relay board for the headlight door operating circuit.

On a side note, I glanced at your build thread - car looks great!

Re: 67 RS headight harness upgrade - adding relays or relay harness

Ok good deal. I will be getting an aftermarket kit not picked one specifically as of yet but yes I will be going that route. I have already installed everything as far as relays and wiring goes out in the engine bay. I'm not too far into it to add anything else so all is good at the moment. I just saw your post and thought it'd be a good time to ask. Thanks for the quick replies.

Re: 67 RS headight harness upgrade - adding relays or relay harness

No problem! I can't swear to it (haven't used an aftermarket electric conversion kit) but electronics have advanced a bit in the past few decades and I can't imagine anyone making a conversion kit with the same shortcoming - the complexity of the '67's electric relay setup just isn't necessary anymore. I think you should be fine as-is.

Re: 67 RS headight harness upgrade

I just got an after market harness that allows the HL switch to operate on lower current (relays) and keeps the HIGH current at the headlamps. My Camaro is an 67 RS/SS. Will I have the same issue with the doors not closing?

Unsure not knowing the specifics but if you're using the original RS door setup with the relay board, I suspect you will have this issue.

Re: 67 RS headight harness upgrade - adding relays or relay harness

Greetings gentlemen and or ladies: I am a new member to this site so please forgive me if I inadvertently step on any toes as that is not my intention. It appears the last post to this thread is slightly over a year old so there is a chance no one will see this. I just received this years Classic Industries annual catalogue in which on page 239 they list items # 14589 for 67 and 68 RS models and # 14590 for 69 vintages. Both conversions are priced at $780. Classic claims that this kit greatly simplifies the door opening /closing through the headlight switch and there are only two wires to connect. I have requested a PDF of the instructions from Classic and if they email it I will post it in this thread. From the product description it appears the hot wire ties into the headlight relay somewhere near the driver side of the radiator and the ground goes to the right (passenger) fender. It appears that the complicated system originally designed by Chevrolet all comes out inclusive of the stop switches and relays under the left fender. I have been struggling for 5 years to get my 67 headlight doors to work without success. Two auto electric shops could not make them work as designed. I like most of you would like to keep my Camaro as original as possible but I like to see where I am going at night more. This system was not in last years catalogue and a quick call to Classic determined that this is a new design and this is the first year it has been marketed. Should I opt to purchase the system I will post items of significance in this thread. Thanks for your time and please drive safely.
