3SGTE Harness Routing and Lengthening Options

[WannabeGT4]

When you all had your harnesses done, did you re-route the harness to exit on the timing belt side instead of the distributor side or did you just lengthen it and run it behind the intake manifold then through the hole in the firewall on the passenger side?

It wouldn't be that difficult to cut open all that looming, route the wiring out the back of it, and have a very clean harness that didn't need to be extended at all.

I did something like that with my harness. You still have to cut and extend a bunch of wires - since the length of the wires are relative to the harness routing.

For example, the 4th injector plug on the JDM harness has the least amount of wire, since the harness enters from the right (when facing the motor)
On the US harnesses, the 1st injector plug has the least wire , since the harness enters from the left.

I have been enable to route the 3rd gen 3SGE wiring into a 6th gen without having to extend the ECU/Dash plugs. You still have to extend the ignitor, coil, CCO and VISC wires, but thats nothing in comparison. Now if only these harnesses were easy to get!

Oh, and I highly recommend running the wires behind the intake manifold instead of through it. Nothing like having to pull the IC, TB, and valve cover to get the wiring harness out - or to get to the injectrors.
