What are these wires?

Hey guys,

Im sorry for the crappy pic, but what are these wires?
Looks to be 3-4 wires and I believe the vacuum tube to the HVAC ? It is going through the firewall just below the passenger side head, right by the trans dipstick tube.




Thanks!

Can't make out **** in the pic, but sounds like you're describing the vacuum line and wires for the HVAC system. The wires go to the blower motor, blower motor resistor pack, and the high speed fan relay.

Thanks Drew!

Yeah I know, and I forgot to describe how it was taken 😅 Pic is taken from underneat up on the passenger side. The bolt is one of the upper trans flange bolts, and the black pipe is the trans dipstick tube, and the wires are going into the fw.

Im chasing this issue seen in my other thread here, where I can’t figure out why my car won’t idle and has no power.. Starting to look for wire shortage and/or ground issues..
