This is my first post contributing versus consuming the fantastic information I find here on NICO. I had not found any document like the one I created so after countless hours of pouring over electrical schematics, multimetering physical connections and transcribing hand-written notes to put this all together I thought I would post it for public consumption.

The document on the link below is a complete cross reference (source->destination) of all the wiring conversion/integration necessary to get a VH45DE into a Z32. Many Nissans are wired in a similar fashion so others may find this document useful as well. This document is intended to be a starting point, so any suggestions on how to improve are always greatly appreciated! Think of it as a Request for Comments (RFC) at this stage.

I am hosting this document on my servers so any changes incorporated will be placed in that document. This way we can have a "single source of truth" versus an attachment that can become outdated.

Caveat: I am waiting for craigztoys (hint-hint) as he's fabbing up my engine mounts and oilpan. With that said the wiring harness has not been tested. Craigztoys is also reviewing this document against his conversion with a 90 motor and we'll make updates as feedback becomes available. I will do the same when the motor is in my Z.

I hope you find this document useful and maybe it can save you the hours of work I put into it!

Good Luck with your projects!

Nick.

Stacey Lynn Childs 1970-2007... Love of my life, my best friend, Heaven's prettiest angel. I miss you so much.

Trust me guys, we have been chatting for a few weeks about this, he has a lot of time in the wiring. He did an amazing job.
Soon there will be 2 450ZX's within a hundred or so miles. i fortell awsome videos in the future.

Again, Thanx nick.

In the fsm's it lists 2 wires for the fpcu on the Z. My z only had 1. 90 na 2+2 Don't remember the color.

There are fan relay outputs from the Q ecu listed in the fsm. My 92 ecu did not have these. I believe infiniti added this feature to 94+. The early Q's have a thermoswitch in the radiators for fan activation.

Craig: Yeah I put the extra narrative at the top and notes, etc. on the bottom before posting the document as you and I have talked about this but it would be difficult for someone reading it for the first time. I fixed the typo on line C that you sent me (long nights) and will be posting the update v2.1 shortly. As for the disclaimer I had to put it in there because while the document makes it easier it's not meant to be a "how to re-wire your car for dummies" - like they say if it was easy everyone would be doing it!

T45: Thank you for the feedback. I had added a bit about the fuel pump on the normaly aspirated Zs but it's buried at the bottom under "notes" (maybe I'll bring it to the top) - I don't believe they used variable fuel pressure so they aren't equipped with that feature (it's actually shown as a whole different setup on the 11x17 wiring diagram supplement that I have). If I'm misunderstanding you let me know and I can update accordingly. As far as the Q45 is there anyway you can elaborate on the thermoswitch (wire color - basic diagram if possible and PM it to me) and I can incorporate this new information into the document (Giving you credit of course - I'm going to add a credits section to the doc).

Once again thanks to everyone.

Nick.
