I haven’t been able to figure this out despite watching videos and reading.

Do I need to do a t-splice with my hot shuttle valve wire into the yellow/green (y/g) wire, or can I safely snip the y/g in two, leaving one end of the y/g dead and one live and do a lineman splice to join it’s live end with my hot shuttle valve wire?

And if it’s the latter, dumb question: which is the live end of the y/g now?

I assume a t-splice would work fine, even if it’s not necessary, but I want to make it nice and neat with shrink tubing if I can do a lineman splice.

 

I think I may have just figured it out mere minutes after posting that question. It looks like it IS safe to cut the y/g and that you just need to splice the hot shuttle valve wire with the part of the y/g going IN TO the aluminum ABS box (no idea what the actual name is for that)

If I’m wrong, let me know so I don’t kill myself or someone else.

Thanks

video and pic I used for reference:

Spliced wire into yellow-green

 

You splice into yellow/green wire side headed back to the SLABS unit. You DO NOT connect it to the side going to the Wabco unit.

 

Phew. Thanks!

Based on that video I thought it it needed to be spliced into this side of the y/g.
