Step 1 has been complete!

the new engine is ready to be cleaned up, wire harness modified, and patrols floor pans repaired (rusted away). Does anyone know of a 3d model of a G60 patrol, specifically the front half with frame rails and body/engine bay? I would love to be able to design some custom motor mounts in CAD.

I have started re-wiring the engine harness, getting it ready for standalone operation, and it is almost done. I am missing the OBD2 plug, but thats very easy to wire in, just 3 wires. Also started taking the unnecessary accessories off the engine, and Ill have to figure out some kind of idler pulley replacement for the power steering pump since I wont be running PS.

Well I found a schematic of some frame dimensions so I made a crude model of the front half of the Patrols frame. Also got an LS engine model, and a bellhousing and trans model. the bellhousing and trans arent exact (621 housing with a T56, whereas ill be using SM465 trans with an old school bellhousing), but it will do just to help with 3d positioning of the engine. This is what I have so far:

I have finished reworking the harness and its ready for "1-wire" operation. Ill just need to get the ECU tuned to remove VATS and emissions, and also program in a fan turn-on signal.

took the gas tank off yesterday, and by the looks of how it was mounted, I don't think its even a Patrol gas tank. previous owner(s) welded in brackets to mount some other gas tank, but it actually fit pretty well. I think I will go ahead and re-use it after I clean all the crap out of it...one question though, is the top hose in this picture simply the tank vent hose?

The filler neck is original, although mounted backwards. Yes, the hose is a vent hose. The other nipple is supposed to have a hose line going to a fitting on top of the gas tank.

What do you mean its mounted backwards? And yes the lower nipple did have a hose going to the top of the tank. I took the picture after I removed the fuel tank and lines.

Looking at the picture again, it seems the angle may have been confusing. It does seem to be mounted in the correct orientation. One thing to double check is that the vent hoses are clear of crud. Mud wasps like to build nests in them, makes filling the fuel tank difficult when it can't vent.

Yeah replacing the vent hoses is definitely on the list once I get that tank modified for EFI fuel delivery and install it back in!

i was finally able to order a bunch of parts today! including all parts needed to rebuild and mate my transmission and transfer case, as well as engine mounts. hopefully those rebuilds will go smooth and i can get everything mated up and into the patrol!

so I have been getting a lot of small things done here and there. cleaned up the engien bay a bit by removing some un-needed brackets, cleaned out the fuel tank (that i'm sure isn't even a Patrol fuel tank), got some wired things labeled like the wiper motor and blower motor, removed sway bars and shocks, etc. A couple "big" things I got done were installing my new brake and clutch master cylinder! Check these out!

I will start another thread for a little how-to write up on these with all the info :)

I also started designing a new gauge panel, which will house speedo, tach, water temp, oil press, and fuel level gauges, as well as the switches for headlights, wipers, heater blower, and ignition key!

if anyone is interested in the CAD file, let me know. I also don't mind changing it up to however you want. But, let me get this part made first to test fit the mounting hole pattern and all that

So I have started making a wiring diagram for the patrol. Going to be using all new wiring throughout the vehicle. I would like to hook up turn signals/hazards and have some questions. I noticed in the wiring diagram, that there's a wire going from the hazard switch, through the brake light switch, to the turn signal switch. whats the point of this? Can I just bypass the brake switch and run the brake light switch circuit separately? Or does the inclusion of the brake light switch in the turn signal circuitry allow the use of a single wire for brake/turn without using any kind of converter? hmm....

Basically you answered it on the last phrase. The turn signal switch is very complicated inside because of that. At the rear lights, brake and turn signal are shared, so everything is isolated at the turn signal switch. Throw the hazard switch in the mix, and it complicates even further.

so if I wanted to leave the hazard switch out, could I still run the brake switch integrated with the turn signal switch? Based on the wiring schematic I found on this forum, I came up with this diagram specifically for the turn signal circuit (attached).

Also, if my color call-outs and numbers on the hazard switch could be double-checked and confirmed I would appreciate it. the diagram I downloaded was a bit grainy!
