anyone have pictures of which connector is which?? I got my harnesses slowly getting torn into.... I know what the IL1 and IL2 look like and identified them, however I'd like to mark the others

I know Bloc must have something ;)
 
do you have EWD? They mark them pretty clearly in there. I have it for all years and can email to you if you pm me your contact info.

You really need to layout how you're going to do fuel pump, GM fuse block before you start tearing into the toyota harness.
 
What @lazy said.

The EWD for your year is the very best resource. If you know where to look, it'll not only say which connectors are used in every circuit (Red/blue>IH2>Yellow), it'll show the cross section, color, and pinout of IH2, as well as IH2's location in the overall vehicle.

I know a lot of people are looking to make this as simple as possible, asking for explicit directions on what wires to connect to what.. but at the end of the day everyone's swap is different, with different wiring needs. Truly understanding the EWD should be part of that process and will absolutely benefit you later when it comes time to troubleshoot something on your rig.

Even after all the work I did to document putting the 97 body on a 94 frame/engine/front clip, it is extremely unlikely that anyone else.. ever.. will do that exact combination of work.

Can anybody help me connect an OEM oil pressure sensor to the dash.

Seems I've seen comments in passing that the connector is picked up in the harness behind the air filter box.

Any suggestions how to find the right pin ?

Sorry I didn't see this sooner.

Stock, the oil pressure signal wire isn't within the main engine wiring harness. It runs across from the oil pressure sender (roughly near the thermostat), in a small harness with the AC clutch wire, through a small gray connector into the front clip harness. I think it then goes through EA4 under the air filter (or did on my LX), which then goes into the firewall under the windshield wiper motor (not the same spot as the engine harness). From there it joins the dash harness and eventually goes to the gauge cluster.

What this means is that there's not an elegant way (that I've found) to get a circuit from the common spots for an oil pressure sender (oil filter area on a LS) across the engine bay to the stock circuit. Tapping in to it near the stock engine harness punch-through would mean opening the dash harness right there and finding the single wire you need. (not easy, or clean). Running the wire through the firewall on the driver's side would mean tapping into the gauge cluster wiring very closely there.. again, not clean.. Plus, as stock, the circuit is shielded.

Haven't decided what I'll be doing with this on mine yet
 
I do however..... I have them on my work computer..... 350 miles away
 
couple quick questions....... pretty positive I know the answer though hahahah just want to be certain

my team 208 harness is pretty straight forward and for the most is stand alone so much that it has its own OBD port
so for me under my scenario (i think i might be crazy to think I really only need to run integrate 2 wires)

My Fuel Green/White wire from the GM side as it is already run through a relay, I should run direct to the fuel pump correct??
+12v Ignition should be coming from E7 Pin 1
Brake signal wire is E7 Pin 14


Tach goes through my Dakota signal converter
Speed is still from my VSS signal wiring as I've left (minus I need to repair the connection......
I feed the fuse panel a direct link from the battery, alternator post direct to battery
I will end up running CEL, Oil, and coolant as well, but Im not concerned with those at the moment as I have them well identified
 
If you're talking about the Green/white wire coming from the green connector, pin 9, it goes to the relay connector to open or close the relay, not supply power to the fuel pump. Not sure what you mean by, "...run direct to the fuel pump..."???? You'll need a good sized wire to go to the fuel pump to get enough ampacity to the pump.

I ran my ignition +12v through my fuse block, but you can rob from E7 pin 1.

Brake signal is constant +12v when not on the brake pedal, interrupted when you hit the brake. This is opposite of the lights. It's on the S13 connector (4 wire going to brake switch), either the R or R-G wire you need to tap. Info here.
 
The harness I bought from Team 208, is meant to go direct to the fuel pump, its a #18 which is all the GM system uses for their fuel pump, BUT I am concerned that # 18 is a little small, I want to run at minimum #10 as per the Aeromotive fuel pump requirements. Ill go pop the top off the fuel tank shortly and take a look, if its not #10 Ill add a waterproof relay and run a a red # 10 and upgrade the ground wire at the tank side as well
(had a closer look at the harness its a #10 coming off the fuse block so yes direct to the pump)

My plan was to steal E7 pin 1, but looking at it, stealing for the fuse box might be just as easy

Hmm good to know about the brake switch, I was thinking I could steal it off E7 - 14 but was just about to dig through the FSM on that to be sure

1. You should probabaly start a new thread. This one is intended to provide general info for vortec swap pinout stuff. You might get more people involved with a thread titled as what you need help with.

2. I think you need to get better info from the harness vendor about what each of these wires needs. "Fuel pump" could be switched 12v direct to the pump (unlikely), or a +12v signal for your own relay, or a ground signal for your own relay. They should have provided some kind of instructions. How to tie the needed signals into a Toyota harness is where the LandCruiser-specific stuff comes in.

How many threads do we need to talk about pinouts as my question has been for the most part, and if you re read what I posted the harness I have is meant to run direct to the pump as I stated its runs its own fuel pump relay (i edited in parentheses that its a #10 wire coming off the harness not a #18) and I would ask Josh more questions at the moment but hes on the lake bed at KOH, he messed up and sent didn't print a fuse/relay diagram for the fuse panel

I got my answer regarding the brake switch and ignition, as you know thats all PINOUT based questions, and YES every build will be different, but sometimes like on this forum when you dig through 100 BUILDS to get the information you need is a little out rageous and confusing
 
A thread for each build is the most logical method, because each build is so unique. IMO threads like this should be general info on the topic originally posted.. not trying to help you figure out the intricacies of YOUR swap harness. In large part because all of this back-and-forth only helps you.. it clutters things up and makes informative threads very difficult to get through for people LIKE YOU that come along later researching what to do about their swap.

Do what you want man.. I'm just suggesting ways to get better help, and help others in your shoes later. And since I detect some impatience, I'll just point out that if you had a very good understanding of EWDs in general (as I suggest to MANY people, not just you), you would have been able to figure out all of this stuff just by looking closely at your swap harness.. no EWD or documentation beyond what was already posted in this thread is needed.
 
wasnt trying to be "impatient" unfortunately a cranky 2 year old, and staring at EWD's has caused me some headaches, than to go into the garage where its cold to tear further into my harness

the other hard part is honestly not having a person to throw ideas off of locally as the guy I would normally go to is "i dont do wires"

I get your point, but a major point was for me, heres a thing, I see 2 sets of a pinouts posted here, all the other ones are clicks to another build..... Which dont get me wrong works, but how hard is a repost of the pinout here

I know myself Ill uploading a Pinout upload shortly of the things I deleted, like e4,e5,e6 being all gone, the only real reference to that here was further up in the thread to "delete" everything from the motor side (pretty self explanatory) but we will want it "easier" thus the desire for "kits"

i will add, it is scarier than heck to look at my IL2 connector and seeing only one wire left on it..... which is part of the CDL
 
You are giving me an idea to document everything I do to my harness. Pics are easy, but organizing it into a coherent post is the hard part
 
EC1 Pinout.webp
I very much appreciate the help from the pinouts in this thread. I may as well add some of my research.

I believe both pin 5 & 6 in @rockrod 's original post are necessary for those with elockers. Not sure, but in any case, do not hurt wiring them in.

Also, for those that may be using this thread to research a future project. I have a good friend that looses his mind, if one cuts a factory harness. However if possible, after the Toyota engine is pulled, I would suggest salvaging the IH1, IH2 and EC1 connectors from the engine compartment side of the respective harnesses. Also there is a short harness that travels from the sensors in the T-case, and ends about at the firewall. I would also suggest salvaging that harness from the old engine. Having these connectors and harness in large part eliminates confusion in wire colors between model years and miss counting pins. You have the colors for your model year, and its just a matter of connecting R on one side to R on the other side, Y to Y, etc.

I have received many requests for this sheet. Probably should have done this long ago. These two images will help those taking on this swap to pinout the IH1 and IH2 connectors that are located behind the glovebox and serve as the main connection to the vehicle harness and vortec harness. My swap was done on a 1994 80 series which uses a separate computer to control the transmission. The later 80s had the TCU built into the engine ECM so they won't have the 3rd plug (IH3). The IH3 is pretty much eliminated on those vehicles that have it unless you want to add in the gear indicator on the dash.

**please note these images apply to the '93/'94 model year trucks**

To help interpret colors, i used the same method as used in the Toyota EWD. Example: 'R - G' would be red with green tracer.

IH1:

IH2:

When I did my swap I relied heavily on the Vortec ecm diagram that is posted on LS1swap.com

Enjoy!

Great info - thanks!

LS1swap.com currently goes to some domain parking site.
lt1swap.com has alot of good information in this vein - maybe the address changed?
 
Reviving an old thread....

The original pinout info posted by @rockrod are no longer available (thanks photobucket...)
Does anyone have them saved, and if so, can you please repost them?

Thanks in advance!

I saved some of the wiring info and added it to a spreadsheet for doing a Gen V swap, also some AC wiring in there too. Let me know if link to spreadsheet doesn't work.
