TR2/3/3A Extra wire in the harness

My TR3A kit came with a new wiring harness. Probable from British Wiring manufactured in the late 1990.

I have been installing it as I go and have found what appears to be an extra wire. The Green/Brown from the flasher unit ends up on the passenger side where the horn and head light connections are made. Then there are 2 Green/Brown wires going from that point to the same point on the driver side.
I will connect the flasher wire to one of the wires that go to the other side where it will be connected to the wires that go up to the indicator switch. That will leave one wire unused.

Are you sure one of them isn't GR instead of GN?

The harnesses are ambidextrous, which means there is a wire that winds up not being used. But I think it should be a GR wire on LHD cars.
 
Thank you.

Good call.

There is a slight difference in the stripe but it is faded red. Did occur to me that it could be LHD and RHD harness.

I am using the diagram put out by Auto-Wire.

Green/White goes to the RH lights which I am taking to be the passenger side.

I think you will find that the harness is destined to be used on lhd and rhd cars, thus there will be several redundant wires which are destined to the indicators and horn controls

Hello James

The harness is 20 years + old so the difference between the brown trace and the red was difficult to see but when the suggestion was made I did a double check and that is the case. One green/Red and one green/brown.

Not being an electrician I am being super careful with this part of the build.

This exact thing happened to me with a new harness (from British Wiring). It is made for left and right hand cars. Drove me nuts, thinking there was a break in my brand new harness! You have to add a bridge connector at the RH fender to send the connection back to the LH wire which connects to the LH signal light.
 
Exactly as original.
