Wiring conventions

[Zedly Serious]

Hi all, I have a new loom from Z Power but all the connecting blocks from the existing associated items to attach to it i.e. switches, ignition etc have been removed. I have the mini connector blocks coming from VWP Ltd and a wiring diagram from the owners manual. I don't want to have to strip back the new loom to see which wires go to which terminal in order to build the new corresponding blocks if avoidable so I was wondering whether or not there is a wiring convention to follow that makes it easy? Thanks

what is a wiring convention ?

[Zedly Serious]

Something along the lines of reading off the wiring diagram from left to right feed wires into the blocks in that order working from bottom left to top right.

I suspect I am clutching at straws and I'll have to match them up by stripping back the new loom to have a look. Just thought I would ask first to see if there is an easy way I'm missing.

Should'nt be a problem with a coloured wiring diagram. I'm the worlds worst at electrics. but managed to swap out GPZ750 switches to work perfectly with a Z650 wiring harness by using the two diagrams and working it out.

that's where they all meet up, talk a lo,t and then change one thing on every model to confuse everybody

Zedly, there are a few, however, there is a lot of confusion when you have..
white, whit/ red trace, yellow/ red trace, red and brown all power supply.
Green is LHS blinker,
Grey is RHS blinker,
Dk blue is headlight Low
Red/black trace Headlight High
Blue/red trace pressure switch,
Pale green/red trace netral switch
Lt blue front brake
Brown horn

Black/ yellow trace and black... Earth.

You can see there is a "sort of" convention.

I think peeling back the insulation will be the easiest option, in the absence of diagrams laying out the specific wiring arrangement of each terminal block. If you want to create some while you are doing you're investigations, it might help someone in the future.

You could just use a circuit tester to check where each terminal on the loom leads to, definitely easier if you have a coloured diagram, but stripping back a bit of the tape would be quickest.

Thanks again all. I will strip the new loom back and match from there.

I will take a note as I do it and if I can come up with a clever way of showing it I'll post it.

No need to strip the loom.
If the loom colours match the wiring diagram you should already know which wire does what and you only need to match the wires from the switches.
Either open the switches to see what colour wire comes from where or use a multimeter or battery and bulb to see which switch activates which pair of wires.
Simple.
