Default Q. Front Lamp Wire Colors

I am terrible at reading wiring diagrams. On the front lamp extension wiring is the "parking" wire brown and the "turn" wire blue or vice-versa? The black is of course ground. This is for a DRL system that I am re-doing, and dismantled after its module failed in 2012, and I can't remember which is which! I'll try again. The system worked well and I do not know why the module failed. Hopefully just a bad part.

Also, that black ground wire (driver's side) feeds into the front wiring harness. Would it hurt (T-section) to also feed it to the front frame? Someone suggested to me that perhaps an inadequate ground was the original problem.

The parking lights are brown and turn signals are dark blue according to the wiring diagram for my '76. I doubt that it changed.

That was my recollection as well. Thanks. I have some wiring, soldering, shrink-wrapping to do tomorrow in the basement. This is one job I can do without having the car out of storage and then just install things when it gets home (I'm trying for mid-April). But temps are above freezing now (just barely in the day) and things are looking up.

I have been on this earth many years and I don't recall a brutal winter like this.

Believe it or not, this does make sense. Bring on spring.



The DRLs run on the bright (turn signal) of the #1157 bulbs. And they are bright. When you actuate a turn signal the other side turns off and then both resume when the turn is completed. They de-activate when headlights are turned on. Pretty sophisticated little module. And in my view a safety feature for these low-profile cars in on-coming traffic.

If it works longer than the last module. Based on communications with colleagues I got a bad one. And I must admit it was replaced under warranty. Of course it will be over a year for me to add the 15-minute finishing touches. I had a really lazy 2013. The weather was discouraging.
