what won't work after a M50 swap

[Hartge H26]

I had a swap done and just want to see what things are not expected to work after the conversion. So far the following don't work:

obc:
fuel range
consumption

fuel consumption on tach

over head board: (lights are on)
engine oil
coolant
Washer fluid

My ac fan comes on but no power to the compressor.

And now I have a power drain somehwere that's killing the battery.

Thanks

Every single one of those things should work. On my car, if I didn't tell you it had an M50 you would never know (except for the extra power).

Your OBC and econometer will read inflated mileage figure due to the larger injectors, but that can be corrected as well.

so how do I start fixing these things... any help is appreciated.

If those items worked before the swap and now they don't work, I would say most of the problem is in your harness adapter. Who did your swap? Sounds like half of your harness wires aren't connected.

not connected.... from the round plug on the firewall
