I bought genuineToyota Lighted Running Boards for by DC. The instructions I got on-line are okay. But I am having trouble finding the right connector to tap.

This is a quote from the actual instructions,
a) Connect one T-Tap to the red wire
located in the drivers side cowl area,
connector S3 pin 2.
b) Connect one T-Tap to the blue/black
wire located in the drivers side cowl
area, connector S3 Pin 1

Anyone know which connector, picture would be great, is S3?

There is a driver's footwell light that I know is the correct circuit, turns off after a few minutes, for the lighted running boards. Just seems like the wire on the footwell light is quite small to add four lights to.

Thanks for any help.
