Thanks for all the responses. Sorry it is a green/blue stripe wire.

The green/blue stripe wire is on the same harness as the alternator and starter. The wire in the back has a a connection that from 2 green wires to one. I figured it was something important. Not sure what year engine was put in. The engine serial number- 18l04691a.

 I think Westerns comment about it being the EGR may be correct

1990 defender 90 300tdi I need some help identifying this wire. Blue/green stripe on the main engine harness. Next in line from the alternator. And the same wire is at the back of the harness. My research says it’s the main harness solenoid connection. I can’t find anywhere to plug it. 
 The motor was swapped to the 300tdi.
