Check it works!
Start the engine and make sure the engine warning light goes OUT
If it doesn't, it's blindingly obvious - a HUGE 'Check Engine' warning comes up, cured by turning off, checking everything and trying again. It can happen if the 'map' is too 'strong' - see next post.
If it doesn't start, something is not plugged in properly.
Turn it all off, check the connections, leave it a couple of minutes (to sort itself out - honestly!) and try again
If all is well, you're ready to go for a spin
You may or may not want to replace the engine cover now, or later
