JP is right as a judgment call. Its not as bad as it first looks.
Being a novice ther is just as much work if not more to do replacing the harness compared to fixing the existing. Fixing it means you need to buy a good set of crimps and the correct bullet connectors to do the job properly.
I have posted up what needs to be done and look at to bring it back to factory specs
At the top where the yellow arrows
point to needs to be dismantled remove the green wire and rejoin the 2 L, (blue) wires.
indicate the main power source to the indiv-cators buy a Ch, (chocolate), wire on the right and a Dg, (dark green), wire on the right. These go through the indicator shaft to the light socket. From the factory they are black in the indicators and have a bullet connector joining them to their prospective colours, See the pic of my Bucket
show the earth/ground contact point under the indicator shaft nut. That black thing is where the wire was. This also shows on the Black arrows
where the Earth/ground wire should be going to in the harness..............Usually they both will go into a triple bullet connector, but as long as they both are connected to the earth/ground circuit thats ok
Green dots.....this conglomeration needs to be removed.........(and nothing should change, meaning everything should be back to factory specs for the harness/loom)...................... if all the other coloured arrows are followed
My concern is where the green joins the blue..did the OP also splicet this to the indicator relay circuit or as you mentioned the indicators are powered all the time and wouldn't they flash???
