brown/blue is ECU light from what I can remember (its been a while)
brown/white is for the diagnostic plug
brown/yellow is also for the diagnostic plug
blue is usually temperature gauge

Don't use the rest as far as I know.

For the boost cut you need to plug the reverse light switch from the Nova loom into the LET loom (black plug) and then the other black plug around that area on the LET loom goes to the reverse light switch in the gearbox. The white plug is for 1st gear boost cut, I just joined the wires together and removed first gear boost cut completely.

Hope this helps
