After quintuple checking all my diagrams, I finished up the last harness for the swap:
Just kidding.
This harness runs from the last one, through the dash, and over to the integration module and DLC connector. Plus a few other doo dads I added.
Finally the wiring is done!
Pro tip - Don't...
I have dozens of wiring schematics and connector pinouts I made which I'll post up once this thing is running and I verify everything is working.
Here's the progress so far. Made my integration harness which plugs into the LS wiring on one end, and connects to the FJ at the other end on IH1 and...
The relay coils only pull 12.5mA and the bulbs are about .1A each. The latching relay states 5mA. I couldn't find specs on the tach adapter. I assumed I had enough overhead to drive the tach adapter and signals. I guess we'll find out. Hopefully I don't beat your 30 second benchmark LOL.
My...
Thanks for the tips! There are definitely a few things I would have done differently if I had to do it again (who knows, maybe it will burn up and I will have to LOL)
I used .5mm traces for the power and ground busses. .254mm for all signals and bulb outputs. I figured that should be enough to...
Next I needed to fit the fuel tank pressure sensor. I could have just teed the charcoal canister hose and ran a hose the sensor, but that's janky. I cut the sensor hole from the top of the GM fuel pump, and drilled a larger hole on top of the fuel pump hanger.
Then I welded the GM piece onto...
Next up was tackling the fuel pump and sending unit. The LS ECU will need to have proper fuel level readings to run and pass the EVAP tests. The FJ fuel gauge sending unit works opposite of the GM unit. I thought I could convert it using an op amp circuit. I know nothing about op amps. I learned...
After all that, I decided I didn’t want a bunch of black boxes hanging under the dash. A tach adapter, a shift indicator adapter, and a cruise control adapter. I would combine them all into one unit. But that would still leave me with 1 black box hanging under the dash. What to do. Then I had an...
After a long hiatus, I am finally getting some progress done again. Unfortunately work, life, and medical stuff put this project on hold. Now that things are in order, and after some subtle (and not so subtle) comments from the GF, it’s time to get this thing finished up.
The next step in the...
Well I'll definitely go with the TYC if this one doesn't keep up. I'm hoping to have it running by the end of the month. We'll be hitting 100+ degrees a plenty during that time. Perfect for seeing what this rad will do with an HD clutch on the LS. It will give me a reason to melt more aluminum...
I'm going to stick with this one and see how it performs first. I'd prefer to have brass over plastic if it will get the job done.
I'm going to make a tray to fit between the expansion tank and firewall. The pics are a bit deceiving. There is a ton of room there. I'll probably increase group...
The heater hoses connected at the heater core:
I installed the radiator and checked fitment. I got all new rubber and mounting hardware from Toyota. I put in the factory fan shroud to see if by some miracle it would work. Unfortunately the shroud sits too far away from the fan, and it's...
I decided to use the GM expansion tank instead of the Toyota overflow setup. I prefer the expansion tank as it's an easy visual indicator of coolant level. It's also the way the engine cooling system was designed on the donor, so might as well keep everything working factory. I made a bracket...
Then I moved onto the airbox. I installed it behind the passenger headlight. It will not fit as it comes out of the donor. There are 2 attachments on the end to draw cold air from the fender. Those had to go.
I also had to remove the upper lid mounting tab that sits next to the radiator for...
Then I made a bracket to install the new fuse box and Electronic Throttle Control module.
And installed using existing bolt holes:
The fuse box and ETC module mounted. The fuse box is a Littlefuse box. It is fully waterproof and has tons of space for relays and fuses. I won't be using...
I got the radiator back all nice and shiny. I and the GF then spent hours straightening every fin the best we could and touching up the paint.
Next was mock up and make brackets for the PCM. Laying everything out, I wanted the PCM behind the driver headlight. I made this crazy ass bracket to...
Well I got a little further on the road to being on the road. I started off by removing the front end components to get a good cleaning done. The previous owner thought a good wash after going off road is not necessary. The whole car was covered with clay dirt everywhere, and the front end was...
I know they allow for intake mods as needed to package engine swaps on OBD1 vehicles (without any posted guidelines, of course). Is that what you're referring to? or do you mean intake mods in general, aside from engine swaps? If the latter, can you point me to where I could find that on CARB...
