Looking for some electrical help. Rocker switch will be an on/off/on (3 position, up middle down)
First, here is what I hope to achieve:
Up (on) will turn on the roof light bar
Middle (off) will be....off!
Down (on) will turn on both the roof and a bumper light bar.
I'll be the first to admit my electrical experience is limited, but I see 2 options. Not sure if they will indeed work or if one is better than. The other.
Option 1: use a 5 pin relay for the bumper light with 2 power outputs (87 and 87a) run a jumper to the roof relay with a diode so that when the switch is down, it powers both lights. The diode should prevent power from traveling back to the bumper relay when the switch is up for the roof light.
Option 2: same concept but run the jumpers and diode on the switch terminals. This seems like it would be better because of lower current at the switch.
Here is the wiring diagram for the switch I'm thinking of using. Note that it does not reflect the use/wiring I'd be doing
And for posterity, here are 2 other switches in case somebody with more know how sees a better way to wire it up.
