I paid to have my harness built. For the most part they did ok. I ended up having to go back and fix quite a few things they got wrong.

I built everything else to make my swap possible.
The shop that did my wiring was Toyota only swaps here in Oregon.

If you get in a pinch you can call them, have a harness built and I would be happy to walk you thru the things I fixed and upgraded from the wiring they will built.

 

After having the harness built the first time I can see now I wish I had just done it myself.

Upon my next Toyota build that gets this engine, I will take care of wiring my self.

 

I think there are guys who make them.

Have you priced them out vs your man hours?

 

the budget just is not there anymore...Tweaked wants $550 if you are able to ship them a complete pair of harnesses..just not feasable for me. I have no choice but to educate myself the best I can and try to fig it out on my own. The rash of mis information, wrong pinouts aaannnd typos on toyotas wiring schematics have made for one hell of a challenge for a guy who had no understanding of 12v dc circuitry what so ever. well..I have studied more in the last month than in my entire life combined and I think I have a decent grasp on how to wire it now. I am gonna make a few changes this morning and see if I am on the right path...

 

does anyone know what you hook IH1 pin 14 B-R wire to? It went to the 3.0 injectors, coil and ignitor from ign key IG2 position. I wired in the ingition main relay from the ls400 which caries the injects, coils and ignitors for the 1uz but it will not fire. I wonder if I can take out the ign relay...off to try that now and see what happens.

 

Got it running and it sounds just like the stang did....threw all the notes from everyone elses builds away and did it how I thought..bam..Roar!

 

Wow nicely done now get us some video and photos!!

 

sweet! lets see some pics.....

this thread was very useful. looking into my very own 1UZ swap into my 93 T4R

 

have a look on my thread I have a diagram there that I stole from someone else. Works great and is very easy.
