Glow plug wiring out of order and diagram

[nikojo]

Is it ok if the glow plugs are wired 'out of order'?

I'm assuming this is more for troubleshooting the harness and that the glow plugs are all activated at the same time.

Also is this diagram accurate??

Just as long as the wire can reach the plug connection. Most direct path with some slack, away from hot parts.

That's the long and short of it, CAMO
