H8 2g flashable ECU in 1G patch harness.

I made this diagram from information available and I would like to hear from someone who actually did this. Does this look right?

Here is a 2g pinout for you to compare it to:

Re: H8 2g flashable ECU in 1G patch harness.

Btw, it looked pretty good to me other than a handful of connectors that you had not defined on the 2g ecu.

Re: H8 2g flashable ECU in 1G patch harness.

I would recommend comparing it to the pinout that I posted, just for good measure as some wisea$$'s arent all that wise!

I started to use this pinout as the 2g reference but then I realized the the 95-97 wiring diagram and 98-99 differ a little. I searched and searched for hours trying to find a 98-99 only pinout and it seems the only one I could find was the one below that compares a 2Ga turbo and a 2Gb spyder.



To make sure that the spyder was the same (minus a few things turbo related of course) as the turbo cars I compared the photo above to this actual 99 GSX wiring diagram sense no one has made an ecu pinout specifically for 2Gb cars. I am gonna take this and make a 98-99 turbo pinout for people so they don't have to spend hours researching it like I did.

The spyder pinout is basically the same as the 98-99 GSX. The only things that were lacking if I remember correctly without double checking is the wastegate solenoid and knock sensor which were added to my pinout.





After researching and comparing for hours, below is the "98-99 H8 ECU into 91-94 pinout" I came up with. This is going to be used on my car so I spent days making this. Researching, getting advice from people who have done the swap already, and researching what those people told me. For anyone considering this, I am confident in my pinout and I am going to use it on my own car.
