Still looking for the adaptor wiring .

Thank you. I see the connector but the fleetwood side pins are all called "plug".

Also I think I may need thicker glasses soon.

You're not alone there , many magnifying glasses and readers of various power scattered around the house and shop.

Thanks so much Skip426. The green wire was my problem. I put the loose green pin in the connector and it feels like a good connection when I tug on it, however when I nick a little of the wire insulation off the wires into and out of the plug I have voltage going in, but nothing coming out. I will go to the auto store tonight but I think this one is solved.

Fingers crossed .

HINT ; resize photos before posting and wait till the loading to the site is complete before closing the attachment box.

Relays for tail/turn signals must be a Fleetwood add on at Newmar didn't use them and no mention of them in the XC wiring schematics ( attached pdf)

End of Freightliner wiring to the rear is a round connector ( left edge of photo ) that sits center of the chassis frame rails . Picture below , everything beyond this connector is coach builder added. Adaptor between round and rectangular connector , rectangular connector ( right side ) is the start of Newmar wiring of the rear cap.

Do you by chance know what the single white wire on the right side of your thumbnail picture is for? I have a single white mystery wire hanging down on the right side in the engine area. I traced it a bit and it is the only wire in a plastic covering which then merges into a bigger plastic covering in front of the engine (cummings 5.9) hearing towards the front. I haven't had the energy to trace it any further. This may be a long shot, but as they say you miss all the shots you don't take.

And thanks for the tips on posting pictures.

I'll get out to the coach in the morning ( if the rain stops ) and have a look , it could be for the back up alarm , but I can't be sure .

EDIT: Got up, looked outside , and had a break in the rain long enough to run to the coach ; that wire is not F/L or Newmar , my install of a ground wire for the toad wiring.
Why did I use white ? It's only been 13 1/2 year you'd think I could remember .
