Hello everyone, I have a 04' vq35de and I've been trying to source a main harness for the new haltech pro plug in. It's going into my 240sx, so there's no need for obd function, vats, etc, just to run it. I'm also going single turbo with a custom manifold so I'll be running a aftermarket wideband, and going with a map setup.

I found one locally last night and was told it was for a de, of course after buying it it was then disclosed that it has the 6 wire o2 sensors and was out of a 05' track model

I've laid out the harness next to a g35 sedan de harness, they're plug for plug other then the 6 wire o2 sensors, is there any other way to confirm it's a rev up or de harness? The ecu pinout doesn't seem to match locations of the haltech pinout so I'm very skeptical if it will work, eve though it's a 05' harness.

(btw I'm looking for the de harness because my g35 sedan harness doesn't have the correct ecu plug)

Thanks for any help!

 

Hey, I have a full engine harness that came off a blown '04 de engine (broken valve). Harness is complete to the ecu connector. Let me know if you need this or i can help in any way.

 

Rev up harness has extra connectors for the exhaust cam phasing.

 

all the years of the Z and G should have the same pinout/ecu connector from 03-06.

The big differences would be that some time in 04 they went to wideband 02 sensors and the revup engine had exhaust cam timing control (may be two extra solenoids and two extra cam pos sensors)

Pins would just not be used, but the numbering and locations for all others should be the same since the UTEC and Haltech work on all the VQ35DE years with the same harness/direction connection to the oem harness.

 

the revup will have 4 rear cam sensors, as well as 1 green and 1 blue cam sensor up front. easiest way to tell.
