Point well taken turbo4x4. I know for sure I can become very tech at time. It is rough for us in the field to talk to people that are not in the line of work we are in. I find people like me that work with , deal with , and whose friends, parents,wives, are all either mechanics. electronics ,machinists., or motor heads, and tradesman all tend to go way to deep for the DIYer, . I don't know anyone that is not in some technical field that I either grew up with or hang out with. We are a scary bunch but we do mean well. Cal, other that looking at this old sketch of the relay I couldn't tell you the numbers. I have used these so many years I just look at the terminals and know what the field coil is and the common , normally open and normally closed . But maybe this sketch will help you understand some of the different things that can be done with this style relay. Some of these relays do not have the 87A terminal that is a connection to 30( common )with no power to 86/85 . And its just showing you what
could be done with the relay depending on how it is connected. Of course from the battery there would be a fuse though its not show, just understood to be there. And the wire from the battery to the switch ( top sketch) in your case would be the ACC connection from behind the headlamp.. Glad you decided to not fiddle with the high beam circuit. And from a safety point of view, if your headlamp system ever does fail, your accessory lamps are now on a different system and will work. I do tend to not realize there are allot of guys that have not learned basic electric and I hope I haven't offended anyone. Gene Kap
