Not sure but I am seeing different part #'s for Cressida and Supra. Best thing I can tell you is to Ohm them out and compare the values.

More progress......sorta. Got the main harness sorted and reinstalled. After using 3 different harness to build one good one. What a nightmare. http://img.photobucket.com/albums/v122/Kckazdude/87%20Supra/Picture032.jpg...

Some pics.

Everything I have ever read about these swaps usually turns into a nightmare. The end result of every one of them has been to source a correct chassis ECU and engine harness. The only thing I know is that power sourcing for the later models changes as well as TPS. I havent been able to source...

I have one loose on my shop floor. WIll post a pic this evening if anyopne else hasnt.

Add dash harness, main harness and both rear body harnesses to the list as well.

^^True, but Hondas were built on a really slow assembly line. :sarcasm::naughty:

Always impressive to watch your car run.

If you have a Honda figured out this Supra will be a walk in the park. As JJ stated it is just a series of small tasks to get it figured out. Anyone with a strong desire and very strong willingness to learn can do it.

Toyotas are much simpler than a Honda in my eyes. Then again, all of them are held together with nuts and bolts.

Dude, that would require like so much work ....and money...and....

I beleive the problem lies in the -0.03 on the right front and the +0.03 on the left front. If both adjustments were set to a - or + on both sides it should track straight.

He asked about timing the engine, not about timing the CPS. Really, if I read through the whole post corrcetly, it appears he wants someone to hold his hand while he does it.

Judging by your reply I would say their first offer was around $1000.

Tach wont do anything until you correct the problem that is causing the code 12. You are not getting a signal from the CPS to the ECU for some reason. Main relay, coils and igniter mean squat for now. Try Ohming out the circuit from the CPS to the ECU...

The first thing that comes to my mind is making a left turn through a busy intersection with a row of SUVs and pick ups in the oncoming left turn lane. if you are fairly cautious in your drivng and take every move a defensively as possible then you could pull it off. However, that also puts you...

Code 12 No 'NE' of 'G' signal to ECU within 2 seconds after engine has been cranked. http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=FI&P=26 I am going to say your CPS wiring is bad. Read here for more information...
