Jc30

Hello! I'm new in here, and I think this is the only place I could find the answer I need.
I just bought a 2002 ls430 and the wiring leading into the #5 coil pack has been pulled out of the connector while I was changing the spark pugs.
I'm confused because I have 2 reds.
Can someone take a picture of the wiring leading into the coil pack?
i really appreciate! Thank you. Please help!

I would pull back the wire sheath to expose more of the two wires. Maybe there is a black line on one of the red wires or something that distinguishes the two.

Did you ever get this resolved? I'm having the EXACT same issue as you had right now (same Yr model, cylinder no., and all). Why the heck did Lexus have TWO red wires going into the connector? That's so strange.

OK, first note the terminal numbers for the connector...

Second, you will notice on the wire diagram below that the red wires on terminal #1 for Coil #3 and Coil #5 are spliced together. You can use a multimeter to identify which of the 2 red wires is shorted/spliced to terminal #1 for coil #3. That's the red wire that will go to terminal #1 for coil #5.

Good luck and let me know if you have questions.
