relay diagrams

im in the shop right now trying to diagnose some elec issues on a project so i come to the forum looking for help.

if you know of a good elec diagram showing pin #'s on relays and a explanation as to what each should be hooked to post it up.

at this time im working with a collection of standard 5 pin relays the switched on/off type used for fog lights, windows, rad fans and such.

so far this is what ive come up with.









im sure you guys have other relay diagrams that could be useful.

Some shitty drawings I made for some other stuff. 4 pin relays are simple and kinda limited, but a 5 pin opens up a lot of opportunities.

First one is for adding lights to the dome lights or (any source of switched power really).

Second is adding lights to turn signal circuits that also turn on with another source of power(in the drawing it is the dome lights).

I just made this quick drawing of how a relay works.

Plus a diagram to wire something to the ignition. In this diagram a radar detector.

I found an example of a fan that is constantly on, unless you flip the switch to turn it off

I go back to these diagrams quite often for reference. Pages 29 & 30 discuss fog lights.
