Just swapped my 96 accord to H22 euro r with stock tranny. I was having issues with my alarm before the swap where my hazards would flash without key in ignition I type in the code and it turns off. Then my speed went out on cluster. Once I did the swap my temperature never engaged then my rpms were next to go. Now I have to lights as far as check engine,abs,brake,etc. But my blinkers to come on and interior lights come on so I do have power. I’ve checked all the fuses they’re all good but I do have a nrg steering wheel and disconnected ignition switch to a push start button straight to the starter. Any one out there know where I should start?

 

I'd start by looking at your alarm control unit's circuit board for any obvious signs of damaged components.. They can cause strange issues when they fail.
