OK, Here are some more updates. This truck is nearing completion.
WIRING
After mounting the engine, we moved on to wiring. A portion of the 3.4L engine harness is routed down the driver side of the engine to power the oxygen sensors and transmission. This portion of the harness runs close to the exhaust in some places. We really took our time to be sure the harness was properly routed and fastened to prevent any movement from our desired routing.
Next we routed the engine harness inside the cab. Before doing so, we remove the oversized Tacoma firewall grommet, fully loom, and tape this portion of the harness. Clearance is very tight under the dash and we want to make sure the wires are fully protected from ?squishing?. We route the engine harness behind the EVAP canister. We find this to be clean, secure and provide the most length possible.
At this time we start the ORS harness install. We connect everything in the P/S kick- panel area and send all the leads on their way to their final destinations. The biggest challenge is cleanly stuffing this and the engine harness up and out of the way to the ECU can be neatly mounted. We carefully stuffed the harness upwards, next to the ?dash? components. We did something a little extra on this one ? we cut a notch in the body to allow part of the ?85 dash harness to tuck neatly and safely behind the ECU. That?s vacuum hose on the edges to protect the wires. :mr-t: At this point we routed the relays from the ORS harness near the evaporator and cleaned everything up.
Nest we fumbled around with the stock and ?01 ECU brackets and got the ECU to neatly bolt up. We?re glad we took our time here, it sure does look stock to us!
