    Trying to ID the wires that run to the integration relay. Specifically from pins 7, 9, and 10.

    Pin 7 is White/Black, Pin 9 is Lt Green/White and Pin 10 is Lt Green/Red.
    Any thoughts??

    W-B is typically ground on Toyotas. Pin 7 of the integration relay is connected to pin 3 of the flasher relay labeled "E"
    Pin 8 is 15A Cig fuse
    Pin 9 connects to plug 1B pin 3 on R/B no. 1 (the relay box that integration relay is attached to) This appears to be the R-W wire for the door courtesy light.

    from the 1996 wiring manual... this is what nzbrock is saying but your image doesn't look anything like the book. Yours shows wires @ 2,3,4,5 and the manual only shows a wire @ 4. I am at a loss for an explanation. My 98 manual shows the exact same thing as the 96 manual.

    Thanks. Understand W/B pin 7 is ground. Pin 9, I was able to follow and it is LT GRN/White and goes to right door courtesy light. Still question pin 10 LT GRN/ Red. (Still learning to read diagram.)

    What I did was upgraded my Tacoma to power door locks and windows. Got wire harness from donor Tacoma (suppose to be 95). Stripped out wires from donor harness that ONLY had a connection to the windows and locks. Threaded them into existing wire harness. Windows and Locks work GREAT. But cannot get Left door courtesy lite to work. The 2 pins on the integration relay that are in question were in addition from the donor harness.
    Pin 5 goes to Dome Light.

    Integration Relay Before Mod as comparison to above illustration of donor wire harness.
