I have a friend with a 1990 Civic DX and we slapped a JDM 1st gen B16. My bud did most of the wiring on it witch seems to be fine.
The only problem that i'm having now is the distributor wires. The engine did not come with a distributor, so we got a B17, 90-91 Teg distributor.

Looking at the engine's harness plugs and the distributor's plugs, the wires don't match color and the distributor has 7 wire, but the car's harness only has 5 wires.

Here are the colors on both distributor and engine harness.

Distributor wire colors:
-White
-White
-White/Green
-Beige/Green
-Beige
-Green/Yellow
-Green

Engine harness wire colors:
-White
-White
-White/Blue
-Orange/Blue
-Orange

How can i get away with using this distributor? What wires go where and how? Please help.
FYI, we will be running the PR3 ecu with this swap.
