weird problem with interior lights

[hari-bhari]

very interesting find off of the12volt.com. anyone know anything about this integration relay:

I actually had the same issue on my 97 Camry. Luckily I have a buddy who's a tech at a Lexus dealer. Here's what I found: That green/red wire you tapped is acutally the negative trigger for the parklights relay. It comes from what's called the integration relay that is a solid state relay. If you put +12V to the green/red in the 4-pin white harness, you will fry the integration relay; trust me, I did it on mine. You can replace the integration relay(I'm gonna get a price on it tomorrow to hopefully replace mine) but you can also jump the green/red wire to the green wire directly adjacent in the plug. The green wire is actually the ground coming from the switch in the column, it goes through the integration relay before going to the park/tail light relay. I'm not sure if this is a permanent solution, but it will work temporarily so you're not driving around with no taillights.
