I have no idea where or how to wire in the rear top marker lights either. Can any one advice ?
Also does anyone know where i can get one new rim and 2 new tires ?
The 4 wires you're seeing for the marker lights are most likely 2 green(+) and 2 white(-)
They wired the markers in a series from different splits. One green/white pair supplies the + and - to the light and the other green/white carries the electric to the next marker light. When you pop off a marker that only has two wires, one green/white pair, that's the end of the run. If you're installing brand new marker lights the + is probably black and the ground is probably white. No matter what color the new lights wires are, the green goes to the bulb mount assembly and the white goes to the wire that is tacked to the light base somewhere. In the end you'll have two splices with three wires into each splice... example 2 greens and a black spliced and 3 whites spliced.
When you're resplicing them be sure to cut a little off the original wire end and unshield the lead so that you're dealing with decent wiring. The splice braid on the end of the original splice is probably corroded and tarnished. In doing that you should have good continuity from run to run unless the wires have been compromised within the run somehow... mice sometimes chew them partially in an unknown spot or a friction point that has rubbed through the shielding is also a cause to a continuity loss.
When you're reattaching the light bases and lenses, make sure you do a good job sealing everything so that water can't find the hole where the wires exit the siding.
As far as the tires, you should be able to see what size they are by the print on the outside wall of the tire near where the rubber meets the rim... example 205-65-14... 205mm tire diameter, 65mm tire width and 14 inch rim diameter. With getting a new wheel(rim) you'll need to note the lug pattern and lug circumference to get a match.
This site should give you somewhat of an idea about sizing your tires and wheels(rims) to get a safe replacement.
If you're not absolutely sure, jack it up and take the wheels with you to a trailer tire store and get a professional opinion on replacement. With an older camper, especially if you're planning on towing it a lot, you may very well want to take it somewhere to have the bearings replaced and repacked and the brakes/drums inspected. Most of the time the reason people are parting with these is the fact that they've been setting for a long time unused, an invitation for unseen problems to develope and surface for the new owner who actually uses the camper.
Hope that helps.
