Need some help with cutting my wiring harness. Light Bar to Relay Box by S-Tech

Hello,
I'm sure this is a very basic question but I thought in collaboration with youtube vids I'd get the correct answer several times. So here's my question that relates to installing a 14" LED light bar with a wiring harness (has 2 fuses/relays+Rocker Switch all in the wiring).
I'm going to be connecting this to my S-Tech Relay box under my hood that runs into the Alpine system. Everything I've done to this point I've learned from the internet or word of mouth. Rookie JK owner if you can't tell but we all gotta start somewhere.
My question is in order to just wire the Light bar into the S-Tech box. All I need is 2 cables total correct? A ground and 1 to go into the '1 of 6' possible female connectors from the Relay Box.

Can I cut the wiring harness to just expose the 3 leads from the light directly. On this one they are
Red
Black
Yellow
Take these 3 cables, Black -ground the thing to the frame and then which wire would I run to the connector? I've looked for a schematic and/or wiring diagram to no luck yet. I'm sure this is so freakin' simple some of you won't reply to the lack of real depth question but this Alpine KAC-001 controller has been nothing but a headache for me.
The tech specs:
2013 Rubicon 10A
Alpine X-209D ->
Alpine KAC 001 controller for the dash ->
S-Tech (SPOD like) Relay box under-hood with 6 outs.

Thank you and I love this forum. Love how people help each other and I rarely see negativity so thank you members. You all rock!

3 leads coming from the light itself? Is this a multi colored bar? Or a multi function (spot/flood that operate separately)?

Multi colored bars usually have constant power (red) wire and switch the grounds which in this case would be the black and yellow wires. Then using the S-Tech would be an issue as it's positive switched.

Knowing this is needed to help. I could be just giving you a bad guess with what I know now.
