Tap into reverse circuit?

hey smart people. who knows where i can find the reverse circuit to tap into? i'd like to use the external trigger function on the switch pros 9100 to switch on my rear squadrons when i shift into reverse.

 

looks like i found it...

I just tapped in at the tailight

 

was looking for something in the engine bay. not wanting run a wire all the back from the switch pros.

 

So did it work out? I’ll eventually want to do this also.

 

didn't get to it yesterday. maybe this afternoon. will keep you posted.

 

works perfectly. details here.

 

Thank you sir

 

Alright Mr smarty pants I have a couple questions for you. So I see you got the reverse connected to your switch pros but why did You go with pink wire(external trigger) and not any other switch of the 1-8. Also I want to do something similar with my fogs. I want to be able to control them with my stalk and then be able to run them anytime with my switch pros any tips?

 

the lights are connected to a switch so i can turn them on manually. the pink wire just picks up the signal for the trigger. the app associates the signal with a switch. you can trigger up to 4 switches from the pink wire.

to use a second trigger, you would use the white wire then turn it on in the app.

so, in your case. pink wire would tap into reverse circuit. in the app, associate trigger #1 with the switch for the reverse lights. the white wire would then tap into whatever circuit turns on the fogs at the stalk. in the app, turn on trigger #2, then associate the switch for your fog lights.

does that make sense? it's also in the manual on page 8, item 9, 'External Trigger'.
