Nice work on the project man, especially on the fabrication of the exhaust and fan shroud. I wish I can weld as good as you. Love the 280z project.

Appreciate it! Need to practice welding the thin stuff more for my next project. At this point this is so close I can almost hear the engine's choppy idle!
 
Alternator/Generator wiring.

Wanted to run this by the experiences guys before I burn my truck to the ground!
What I found is that Toyota generator wiring has all needed wires for GM alternator. After checking with Toyota EWD I wired IG to IG, L to L, S to S.
Should be goo to go!

A question:
Is the #1 wire (White) that goes to the battery and to the fuse block thick enough as a charge wire for the battery or I need to run a separate heavy gauge wire from the main post on the Alternator to the battery?

Appreciate your help!

Here it is... finally!!!
Holley has to learn, so things aren't really run smoth yet.
You, guys, were right it is loud AF. Ordered something else to add to the existing system. Will report back!
Had one leak at oil pressure sensor, and one of the fuel like fittings wasn't tightened. All else seems to be ok. Will test drive tomorrow!

LS swap in FZJ80
 
A little update:
Everything is back together and I have been taking the truck out for short shakedown runs here and there. Everything is looking good!
Things to sort out:
1. Speedo isn't working. It quit a few months before the swap started and I suspect it's the sensor itself. I might have damaged it on one of the last trips Inhad that speing. It spins inside it's mounting hole and I donnot remember it doing it.
2. Tachometer isn't hooked up and I haven't done any recent research on how to hook up, yet. From what I remember dakota digital is needed even with Holley Terminator.
3. Strange shifter problem. I can get out of park only when lever lock override button is pressed. Need to see about that. Most likely will need to run a brake light signal wire from E7 plug. Currently that wire is connected to Holley transmission harness that needs that signal to unlock the torque converter when you press the brake pedal.
4. Need to finish the air filter box. Silicone coupler finally arrived and I need to hook everything up.
5. Toyota temp gauge. It bugs me not to have that needle showing something! Might just buy a modified temp senson from Matt, since I already did the wiring.

Here is a small video of it running and revving up a little.

That is a nice ride. I used a Dakota box as well. I tried to connect the Dakota high voltage output wire to the black wire from the check data, that didn't work for me so I tapped it to the wire from the combination gauge. In addition, I ran the positive wire (from vehicle speed sensor) to the Red Orange wire and speedometer works for me. There may be a break in your ground or power wire from your speedometer sensor. Some people said you don't have to use the Dakota box for the tac to work.

Thank you for the information!
 
Did you end up using the Holley terminator? I would be tempted to just use a screen off of it for tach etc. save yourself a headache. Digital screen more likely to be accurate. At least drive it for awhile until you want to tear into it again.

Yes, I used Holley Terminator. 3.5" screen is up an running and does have everything I need. Just being a little OCD about it!
 
1) Speedometer shouldn't be swap related.

2) Tach is easy, depending on GM ECM being used. Toyota's tach can be adjusted for different number of cylinder pulses or most GM ECMs can change its tach pulse frequency to match the Toyota tach (3/rev).

You do need to either pull-up the GM 5V pulses to 12V, or modify the Toyota tach to accept 5V pulses. You can spend money of a Dakota Digital tach converter, but not necessary and just adds more complication and cost to your swap.

Much cleaner done this way and one less thing to go wrong down the road.

3) Toyota Shift Lock Controller does need to see the brake light switch and the transmission in Park/Neutral.

5) I use the modified temp sensor from Matt and it works well. Marks 4WD adapter caused interference issues due to its added length.

Speedometer stopped working a few months prior to the swap. If my Toyota VSS in the transfer case is toast I might be able to grab the signal from GM's sensor mounted in the Marks adapter. Holley needed that for transmission control.

Appreciate the tachometer info. Need to do some more research on how to make it work with Holley.

Already have the wires marked for the shifter lock. Need to make splices/connections.

Matt's temp sensor is definitely the way to go.
 
A little update and some head scratchers.
I extended the exhaust all the way to the back and added a chambered muffler. The sound level has mellowed down a bit if you stay out of it. I can even call it pleasant on the highway. Have been taking the truck out every evening for 15-20 mile drives and everything is good. Will have a light snow-wheeling trip this week.
A couple of problems that I can't fix for now.

1. The center diff locks as it should when I put the transfer case in 4L, but the dash light doesn't come on. It will no longer activate with the switch when the transfer case is in 4H. Can't seem to figure out the wiring diagram 100% for now, but it looks like I need to add a signal wire form P/N switch to the IH2 connector (Red-blue wire).

2. Also, when switching from 4H to 4L and other way around it will not go in gear. The input gear is spinning and not letting me to go between H and L unless I turn the engine off.

Any help or advice will be greatly appreciated!
 
I only followed recently, so I am not sure what was done, or how it was done.

1. I would short the connectors to check bulb/wiring. All those t-case wires are not part of the swap and should have been retained.
2. Sounds like a transmission issue. Are you not in park/neutral when switching 4H <-> 4L?
