Mine has Yellow & Yellow/White for the middle connector.

Which wire goes to pin (#1 or #2) for "in" ?
I searched, but some shows Yellow on pin 1. Some pictures show Yellow/White on pin 1.

New connector is on the way, but want to figure it out.

I think I found the correct color.
Pin 1 is Yellow
Pin 2 is Yellow/White

That looks like the 1998 diagram? In 1999 the wire colours and pin assignments to the ECU are different between DENSO and ME7 engine management. Your XC will have ME7 , please confirm

Here is the 1999 story…

I got the diagram from service manual 3941202 Section 3 for the wiring of 99 C/S/V70.
Denso is for non turbo. So, mine should be ME7 as it also is listed as ME7 at my IPD account.
