- 2002 1.9 tdi swapped into a 1993 4runner, Malone stage 4 tune, bosio 764 injectors, vnt17 turbo, 3 bar map sensor
I have completed most of the grunt work that comes with my engine swap. The most troubling factor left for me is the wiring harness. I've read many threads and decided to go with the less cluttered look of trying to narrow down the harness to the bare minimum while still being able to communicate via vcds.
First some background. The donor vehicle is a 1993 Toyota 4runner v6 and the engine that will go in it is a 2002 1.9 TDI from a manual Volkswagen bug. I've got a Malone stage 4 tune with an immobilizer and EGR delete I've also put on a vnt 17 turbo as well as upgraded injectors and map 3 bar sensor.
When I first hooked it up to vcds I could communicate with it just fine but was not able to start it. After I let it sit for a couple months I came back to it and can no longer communicate for whatever reason. But one thing new that was happening was that my relay 109 was clicking rapidly. Tried a bran new oem relay and the same thing happened.
I've taken some pics to help in the discussion of where I'm at. Can I get any conformation on weather the wiring harness is correct or not? Also any ideas as to the rapid clicking on relay 109?
Here is a pick of the half of the wiring harness that I delta with. The other half is unchanged.
Below are some closer look photos
This is a photo of my fuse box that I basically kept the 4 essential fusible connections from the original box and replaced it with a cleaner more compact one.
I will try and get some more photos up as soon as I figure out how.
