great job on the harness
@@LunarOutlawsGarage Thank you! How’s your supercharged Supra coming along?
really nice, you should post where you bought the materials too
@@zazzn, thank you for the feedback. Please take a look at my other harness videos, I did list materials in the description section.
You're smarter than i am lol. I made my own harness too but i literally pinned every single wire on the emu black connectors and i have no idea why 😂
After i got it running i had to depin so many of the unused wires 🤦♂️
Great work, that takes alot of patience and brains to redo the whole thing by yourself! I'm currently doing a 1jz VVTi swap on mine. Where did you get the pin outs? Do you have a website? I've got most of them but I cant find the Supra fuse box pin out (6 pin yellow connector) and the 3 extra plugs in the car next to the ECU. I would appreciate any tips
@@animusrare, thank you for the feedback. It definitely takes patience. This website was the best reference I could find for harnessing. You literally can grab every wire you need from the Supra in three body harnesses.

@@SupraSeth This is very helpful thank you, the three body harnesses you mention, do you mean the 3 in the car plus the fuse/relay box?
@@animusrare, M1 and B1 are in the dash area above the glovebox. C1 is a plug by the engine fuse box that gives you what you need for powering the ECU and sensors. You power/ trigger the Main EFI relay with the ECU. Switched power comes from pin 16 on B1. Starter signal is on pin 12 on B1. I added a circuit in my engine fuse box for the fuel pump. Take a look at my playlist, I have multiple videos on the integration. Let me know how things work out.
You need to sell these kits…. I need one asap
@@donovan007007, If I built harnesses they would probably be too expensive and not competitive with the other providers. When I built a second harness to include DBW, I had no problem selling the first harness. Are you finding any for sale for your build?
@ no I’m not, still looking. Of course the bane of any car guys building is usually the wiring when it comes to major swaps. Was looking for a plug and play harness. I have a 90 manual turbo 7m (all white package), and wanting to put in my built 2Jz-Gte. I have not received back my built trans yet but that’ll be here in a month or so hopefully. Still need to buy a diff and have it built also. I was hoping to do the entire drive train swap and have ready all harness kits for complete install altogether. At this point, I might have to pay for your services no matter the cost. Give me a bit and if I haven’t found a solution by the time I get my trans, I’ll hit you up and see what you need from me to start the harness project. I just knew I was going to run into this issue but knocking out the main parts first was going to give me time to sort the harness.
@@donovan007007, sounds good, I would want to know more details about your build.
