The 22RE trucks and 4runners have a lot more wiring in the harnesses than the carbureted models. The 22RE engine compartment has three harness branches coming from the cab to the engine compartment as opposed to only two in the carbed trucks. In the pictures below you can see how the thre branches enter the engine compartment. I had to remove the heater blower to get access to the branch that passes through firewall directly into the engine comparment. I'm taking the A/C from this 4runner for he truck so I pulled that out too.

The three engine compartment harnesses:

• The ECU harness
  Passenger Side Fender Harness (The Power Harness)
  Drivers Side Fender Harness (The Accessory Harness)

I'll have some pictures of the body harnesses tomorrow. -- Matt
