So my temp gauge on the dash isn't working along with the speedo even when car is really hot and the fan doesn't seem to be kick in at all, I've read that the yellow/green wire is the wire that sends the signal to the temp gauge on cluster and this wire on my loom is just hanging there without a plug on the end.... Its been like this ever since we done the engine swap near January time and the temp gauge worked perfectly before but its just stopped working completely, there's also no vtec engagement at all and after say 20 minutes of driving the radiator pipes are under a fair ammount of pressure please help not wanting to melt my engine, its a jdm b16a swapped into an ej9

 

The temp sensor on side of the block should have a plug on it. If it doesnt then I sugg3st you look for a fix. The speedo is prob the vss on the trans. Known for corrosion. The vss also will prevent vtec from working.

If the fans arent coming on there a good possibility you already screwed something up.

STOP driving the car and figure out whats wrong.
