Toyota 3RZ 4 Cylinder Engine Swap - More Turtle Power
|
When it came to electrical, the 3RZ is running a new computer and a mixture of wiring. From Clampy came the wiring to feed all the gauges and lights, from the Tacoma came the wiring to run fuel injection, and a new wiring harness from Off Road Solutions connected the other two. The Off Road Solutions harness picks up the speed-sensor signal from the back of the speedometer gauge to tell the ECM what speed the vehicle is moving. All the terminal ends are labeled, sealed with heat shrink, wrapped in wire loom, and ready to plug in, plus the monster harness can be custom-ordered to include lights, horn, radio, gauges, and so on.
