The Roadlamp relay plugs into that connector on 70 Cudas'
Correct !!! Which leads us to the next step on that connector...As Snoopy has pointed out if the car has road lamps the wiring harness from the lamps plug into that connector...I'm going to borrow two pics that Beepbeep{thanks Beepbeep !} has posted in the past instead of going out and standing on my head for the pics... Here's another shot of that busy connector.... .... And here's a pic of the 70 roadlamp harness....Take note that the connector marked "headlight warning buzzer" does in fact plug into that connector and in turn has another plug for the diode to do it's job...
and based on this post, its obvious that yjr little 4" harness I described above is correct cause it has the feed for the road lamps. All I need is the diode setp to replace the jimmy rigged real that I have and that wont be a problem since I can just use that mystery harness that goes to the mystery relay I have.
