Hello fellow people who get headaches from hondas from time to time,

I have a 2000 accord 2.3L lx trim originally auto. Converted it to 5 speed man. Now! swaped the ecu to a p72 ob1. Yes, i used Obd2b to obd1 harness.
So remember i have the original auto harness, then switched to obd1. Now!

Problem 1: Speedometer is a no go. Did the D10 D1 and D2 wiring, nothing. Then went ahead and did the A9 to C23. Nothing. Then Grounded to a solid groud on body. Nothing. Doesnt anyone see what i missed or did wrong?

Problem 2: thermostat not working either.

Problem 3: converted the ICV to a 2 wire, worked awesome but i still get a SMALL bumping idle tuning issue?

Thank you for your experience guys/ and girls.
