- This kit is made for 1999-2002 4Runners, this kit will NOT work on 1996-1998 4Runners. Starting in 1999, Toyota switched to a digital odometer and the way the fuel sending unit works is by a digital reference from the dash, and the sending unit geometry and electronics completely changed. The bracket and wiring harnesses in this kit have been designed to only work with these 1999-2002 Toyota sending units. If you have a 1996-1998 4Runner and want your factory fuel gauge to work after swapping fuel tanks, I believe you can get your gauge to work (minus the low fuel light) by using a fuel calibration device (see Classic Instruments Fuel Link, MeterMatch Fuel Gauge Interface Module, or similar device).
- The bracket only works with the Toyota Sending Unit P/N 83320-35590 (1999-2001 model years) or P/N 83320-35620 (2002 model year). Sometime in late 2000, Toyota had a service bulletin TSB EL010–00, which replaced the (sometimes defective) sending unit P/N 83320-35530 with P/N 83320-35590. The geometry changed between these two versions, the bracket in this kit is designed to fit the later version. So if you have a model year 2002, your OEM unit should work. If you have a 1999-2001 model year and had your vehicle serviced from TSB EL010–00, then your sending unit will work. Some 2001 model years will have the old unit and some will have the new unit, it depends on the production date. If you have a 1999-2000 model year and have not had your vehicle serviced from TSB EL010–00, you need to purchase the new sending unit (P/N 83320-35590).

for this the TSB asks to replace a circuit board behind the speedo? Is that actually necessary? I have a 99 and I'm sure i have the older sender with the newer one on order
