Anyone know how to find out the part # for an LEXUS GX 470 2005 ? I need the maf/iat harness as I am about to perform the Air injection bypass for the failed secondary air pumps. Did anyone attempt to rig one up themselves? Need the wiring info as well to connect the resistor to.

If you can fool the ecu/computer into thinking it's all okay.. at a certain temp the pumps never come on. Apparently this is a common problem in Tundras and most 4.7l vvti toyotas. Anyone here do this?
