TRD Pro light bar Switch P/N

Here are my findings when bench testing.

If using a non canbus light bar you can definitely use an OEM switch.

Same tech as my 96 Civic using an OEM momentary switch to light up my rear fog.

Parts list: OEM switch, PAC TR7, SPDT relay, and simulator box used for demonstration

Cool! I've been hesitating to add the OEM switch but would love to run my lightbars with that instead of my aftermarket switch. Do you have a detailed write-up somewhere with exact connections?

 

No detailed instructions.
The switch portion should be considered of as 2 pins (neg/pos input/output) to simplify the thought process.
When PAC TR7 module is energized it will allow a pulsed input to latch/unlatch a relay. The relay output will be wired to the light bar.
