Im looking for a place/person that can do 1UZ wiring for me. My cars an 89 coupe.
If anyone knows of anyone that can and has done the 1UZ wiring before, plz let me know.
Jake
pm corymcarthur this guy knows his wiring dont know if hes has done a 1UZ though
Alright thanks, will do
do it yourself. wiring is easy enough once you find the wiring pinouts.
Im actually not too bad with wiring but this thread just freaks me out
If I can find a simple how to then I will probably do it myself.
+1 for cory. Busy guy, but good at what he does. Has helped me and a number of friends out in the past.
Holy crap! I see what you mean about needing help!
I think there are companies that will do the harness for you on the net. I saw a couple, but can’t remember where I saw them. Do a search.
Edit: wiringspecialties.com Plug and play harnesses
Thanks
I sent cory a PM.
I emailed wiringspecialties.com and they got back to me within 2 minutes saying they dont do 1UZ… thanks tho
Well if your decent at wiring, get the correct wiring diagrams for both and connect the wires needed to run. If your not connecting the dash or anything it shouldn’t be all that difficult. Realistically you can run the engine on 4 wires.
Its going to be my DD/drift car so I need the dash. If anyone knows of any diagrams let me know
