Wiring an ECT button

Hello y’all, trying to put some DD fog lights on my 98. Anybody ever use this button for that application? What’s the 4th wire for? And anyone know where to buy a pigtail by itself? Or connect to those pins

thanks In advance

 

Pin 2 and Pin 3 make your switch circuit
the other 2 will just be for lighting

 

Ayyyy ok, any chance u know about where to buy those connectors?

 

Electronically Controlled Transmission Pattern Select SW
90980−10601
You'll also need the pins and wires. These come already crimped.(5)
82998-12170

It would definitely be cheaper to just find one in a junkyard

Got the first number from the part_number_of_connectors file
Got the 2nd number by cross referencing the 2nd part (10601) in the 2nd file.

 

Remember to figure if the switch will handle the current draw of the foglights.

Do you plan on using a relay and proper circuit protection??

 

protection? Who needs that? And yeah I would get the DD harness so that comes with a relay right?
