Can you please help identify which ECU should be used on an 89 Accord LXi with Automatic Transmission?

I have located two, but do not know if they are the correct ones.

Y1 37820 PJO A04 KA KC

Y1 37820 PJO 663 KA

Thanks.

any 88-89 fuel injected car computer will work, there is no difference between the 5 speed and auto ecus. 86-7 ecus are different but you could use one but youre much better off with an 88-89

Hey bro put the right computer in your car. Trust me i know from exprenice. I had the second computer you listed in my 89 lx-i and it ran like shit! Eacv, 02 sensors, and the egr weren't working. The car would turn off with the ac on and lacked alot of power. It also ran to rich. Just look in your local junk yards until you find a 89' lx-i computer. You will be sorry if you don't take my advice. Promise. The right number should be-37820 PJO AO3.

then you had an 86-87 computer because that didnt have eacv and only had 1 o2 sensor, and i think the egr solenoid was wired differently because 86-87 had a different emission control box. Hes right, 86-87 computer will make the car run but 88-89 is what you really want.

AccordEpicenter, the 88 and 89 are different too!! Compare the pinouts.
