Title: British Wiring harness
Post by: Runningwild on Saturday,September 22, 2018, 05:38:43 PM
I’m installing a new British wiring harness and have a few questions before I call them on Monday.
Picture #1 shows 2 red wires coming into a connector. One red wire is supposed to go to the right tail light and the other goes to the left side.  Is there a 2 into 1 plug in - to come out of this.
Picture #2 shows the tail light. I guess I’m supposed to re wire the assembly and plug it into the harness.  Those wires weren’t included. Has anyone done a British wire harness?  Any suggestions?
Thanks. Tom. Any suggestions are appreciated

I like the blow up of the wiring harness!

The tail lamp has its own wires and you may have to install bullet connectors on them so they can be plugged into the connector on your wiring harness. r.d. Has them along with a tool to crimp them. Does that help?

Personally, I hate those bullet connectors and although I didn't convert even most of mine, if I had it to do again, I would convert to spade lug connections.

Thanks. The wires on the light assembly are very corroded. I’ll ask British Wiring to send me a few feet of each of the rear light colored wires. The front lights are new and have new wires.
I’ll switch to spade connectors.

The wires are probably ok, they don't look brittle.  Clean them up with paint thinner and fit new bullet connectors and you'll be fine.

The lights themselves may not have matching wire colours.  For example, the park light circuit uses a red wire but some lights have the red wire as the brake light.  Test the light first to confirm.

My comments are for the stock wiring harness, the  S2 and TC harness should be very similar except for maybe the wiring color but should also apply to the British wiring harness

Both my S2 and TCS have four connectors, three dual and one single bullet connector for each rear light as the S2 wiring diagram indicates. Unfortunately the TC wiring diagram do not show the connectors. Assuming that the British harness has the same color as your original car, you should be able to figure out which wire goes where. The leads from the rear light assembly plugs directly into the female bullet connector on the harness.

On your picture of the connector with the two red leads, one lead provides power to the connector whole the other red lead is daisy chained to supply power to the other side rear light assembly. The side marker leads plugs into one outlet whiles the rear tail light lead plugs into the second. My picture shows the setup.

Thanks Joji. I see why there are 2 connectors on the red wire. My car doesn’t have side lights. Non federal car. I’ll just plug the extra one. I do have side lights on the front though. 

On the voltage stabilizer there are 4 connectors.  I’ll only use 2. I should cover the 2 open ones right?
Thanks. Tom

Put your two wires on the outside connectors and that should be fine.

Runningwild,
   You mentioned you purchased a new harness so I have a question about the wire color coding. Are they , British wiring , using Lotus Sb triple stripe  below method or original 26 different wire colors?

If you look at his posted photos, his harness has the earlier wiring with the wire having a uniform colour and a contrasting stripe.

Thanks for clearing that up.

I really didn’t know that the first picture was your new or old harness since the one on the bench next to the schematic, which is definitely new but blurry.
