Toyota 1HD-FTE Conversion Wiring Harness for DIY.
Toyota 1HD-FTE Conversion Wiring Harness for DIY.
NOTE: Doesn’t include engine harness, alternator harness or starter wire harness.
We have developed these harnesses for our own use when doing FTE engine swaps to simplify the wiring side of things and are suited to early manual transmission (or those with standalone auto computer) swaps. The way we do it, isn’t the only way, but the one that make most sense to us.
For the early model 105 (pre mid 2002) these come with a harness that connects into the factory fuse box so that fuses and relays in there can be (instead of taking feeds and mounting relays in the glovebox space).
If you have a late (post mid 2002) model HZJ105 want to connect the relays into the fuse box, this is possible, but (to get the connectors) its best to find a late model HDJ100 engine bay loom. We have a cut down sample harness for this that can be borrowed (deposit required) to see how to install in the fuse box.
If you are wanting to install in the 80 series, we have instructions and a diagram on how to connect the wiring using std spade connectors.
We want to have
FTE engine with electronic pump fitted
the engine harness from an HDJ100
alternator harness from HDJ100 or HZJ105
HDJ100 starter motor loom, which also has connection from engine harness to side of fuse box (for starter activation and injection pump control)
we don’t need to remove the dash or engine bay harnesses.
Also comes with the harness that runs across the dash so no need to strip the original dash harness and only need to remove the glovebox, radio and climate control components, then panels under the steering column.
If you have a FZJ105 then the immobiliser can be used for the HDJ100 ECU and the tachometer signal is the same.
If you are installing into the HZJ105 then a tachometer adjuster (not supplied) needs to be installed and the immobiliser will not work and you need to either
Use a ECU without an immobiliser (HDJ79 or some import HDJ100)
Install the key and immobiliser from the donor vehicle and correctly wire in - we can provide information to do this with the above purchase. If the same generation as the donor then you can reprogram the original keys to function the immobiliser.
Have an immobiliser delete done to the ECU.
