im trying to work out what the wiring plan is on my 2013 expanda. It has the 12 pin plug, and I'm wiring up a new car so need to know what the 5 top pins do so the dealer can fit the car correctly.
The Jayco owners book has a plan, which states the following -
8- Battery/electric witch
9- Auxileries, etc. battery feed
10- earth return
11- rear fog lamp
12- spare

However... In the inside of the manual, the original over (I presume) has hand written the following-
+ pin 9 and -pin 10 Fridge
+ pin 2 and -pin 3. Hotline

So, do I give the dealer the original jayco plan? Or does it look like he's changed the mapping to cut out the battery feed and goes straight to fridge?

Looks the same, ie 3 and 10 are still both being used as earth returns (3 for the lights and battery and 10 for the fridge) whilst 2 and 9 are positive supplies, 2 for the battery and 9 for the fridge.

Hey @Jimbo

Not sure if this helps, this is what we were told to use which the installer wired up

Same for us.

We passed it on to auto electrician and he seemed to sort it out.

One of those jobs you leave to experts in our case. I'd hate to muck around with it.

And he's insured!
